The graph of this equation will be a straight line with a slope of 1/2 and a y-intercept of -5/6.
To solve the given linear equation, we can use the method of isolating the variable on one side of the equation. Here are the steps to solve the equation:
Step 1: Start with the given equation: -3x + 6y = -5
Step 2: Isolate the variable on one side of the equation. We can do this by adding 3x to both sides of the equation:
-3x + 6y + 3x = -5 + 3x
Simplifying the equation gives us:
6y = 3x - 5
Step 3: Now, we can isolate the y variable by dividing both sides of the equation by 6:
(6y)/6 = (3x - 5)/6
Simplifying the equation gives us:
y = (3/6)x - (5/6)
Step 4: Simplify the fractions by reducing them:
y = (1/2)x - (5/6)
This is the final solution of the given linear equation. The graph of this equation will be a straight line with a slope of 1/2 and a y-intercept of -5/6.

what type of transformation has occurred from f(x) to g(x) on the graph
a)cant be determined
b)rotation
c) reflection
d) vertical translation
The solution is, it represents a vertical translation, and value is (d) k = 8.
What is transformation?Transformations are changes done in the shapes on a coordinate plane by rotation, reflection or translation.
here, we have,
Translations of various kinds are often most easily seen by comparing points where the graph has a distinctive feature. On this graph, that is the vertex.
When looking at the graph we can discard 2 of the options, these are rotation (as they are parallel, it is impossible to find a rotation axis) and reflection. We can observe that it occur a translation. To know what kind of translation happened, let's look at the y intercept of both lines.
For f(x) the y intercept is 0 and for g(x) the y intercept is -4, it means it occured a vertical translation down 4 units.
so, we have,
The value k in the equation ...
g(x) = f(x) +k
represents a vertical translation by k units.
The vertex coordinates for f(x) and g(x) are ...
f(x): vertex = (-3, -3)
g(x): vertex = (-3, 5)
This means ...
f(-3) = -3
g(-3) = 5 = f(-3) +k = -3 +8
⇒ k = 8
Hence, The solution is, it represents a vertical translation, and value is (d) k = 8.

How to find the distance between two points?To find the distance between two points, we use the distance formula:
distance = √ (x₂ – x₁)² + (y₂ – y₁) ²
We can calculate the distances between each pair of points and check if any of them are equal to 4.
The distances between the following pairs of points are 4 units:
Point X (3,9) and Point W (5,0): distance = √((5 - 3)² + (0 - 9)²) = √52 = 4.12
Point T (5,0) and Point S (-1,0): distance = √((-1 - 5)² + (0 - 0)²) = √36 = 6
Point T (5,0) and Point S (-3,0): distance = √((-3 - 5)² + (0 - 0)²) = √64 = 8
Point R (1,6) and Point Q (-1,2): distance = √((-1 - 1)² + (2 - 6)²) = √20 = 4.47
Point P (-1,0) and Point O (0,9): distance = √((0 - (-1))² + (9 - 0)²) = √82 = 9.06
Therefore, the only sets of points that have a distance of exactly 4 units between them are Point X and Point W, and Point T and Point S.

A stadium has 10,500 seats and eight VIP boxes. The stadium is divided into 12 equal sections to premium sections and 10 standard sections. A seat at the premium section cost $48 per game. AC at the standard section cost $27 per game.  how many more seats are there in each section? If all the seats in the premium section are sold out for a game how many will the stadium get from those tickets sales? PLEASE HELP 44 POINTS!
Answer:
There are 875 seats. The stadium got $168,000 from the tickets.
Step-by-step explanation:
So there is more than one question so let's break them down one by one
1). How many seats are there in each section? So the stadium is divided into 12 sections and 8 are VIP boxes so 12 - 8 = 4 so there are 4 non-VIP sections. Now to find out how many seats are in each section we need to divide the number of seats by the number of sections which would be 10,500 ÷ 12 = 875.
2). If all the seats in the premium section are sold out for the game how many will the stadium get from those ticket sales? So first we need to find out how many seats there are in the premium section, we already know that there are 4 premium sections and we also know that there are 875 seats in each section. Multiply the number of sections by the number of seats 4 x 875 = 3,500 now multiply the number of seats by the cost of the seat 3,500 x $48 = $168,000
So the answers are $168,000 and 875 seats

Shaquana's car used 8 gallons of gas to drive 312 miles. Fill out a table of equivalent ratios and plot the points on the coordinate axes provided.
Answer: See attached.
Step-by-step explanation:
First, we will find the unit rate by dividing.
312 miles / 8 gallons = 39 miles per gallon
Then, we can fill out the other values using this unit rate.
39 miles / 39 miles per gallon = 1 gallon
3 gallons * 39 miles per gallon = 117 miles
Lastly, we will use these two equivalent ratios we found above to fill out the table and then plot the points. See attached.
The table shows the distance a runner has traveled y, in miles, x minutes after the start of a race. What is the runner's average rate of change, in miles per minute, from 60 to 120 minutes?
Time (min) Distance (miles)
0 0
30 3. 48
60 6. 42
90 9. 18
120 12. 0
The runner's average rate of change from 60 to 120 minutes is 0.093 miles per minute based on the given information.
Given that,
In the table, it shows the distance a runner has traveled.
The time (in minutes) and distance (in miles) values are as follows:
0 minutes: 0 miles
30 minutes: 3.48 miles
60 minutes: 6.42 miles
90 minutes: 9.18 miles
120 minutes: 12.0 miles
To find the runner's average rate of change from 60 to 120 minutes,
Use the formula:
The average rate of change = (Change in the distance) / (Change in time)
From the table,
At 60 minutes:
The runner has traveled 6.42 miles,
And at 120 minutes:
The runner has traveled 12.0 miles.
So, the change in distance is 12.0 miles - 6.42 miles = 5.58 miles.
The change in time is 120 minutes - 60 minutes = 60 minutes.
Now, we can calculate the average rate of change:
The average rate of change = 5.58 miles / 60 minutes
The average rate of change = 0.093 miles per minute.
Hence,
The runner's average rate of change from 60 to 120 minutes is 0.093 miles per minute.

Solve the following system of linear inequalities: \[ \begin{array}{l} -2 x-y1 \end{array} \]
To solve the system of linear inequalities, we need to graph each inequality and find the region that satisfies both inequalities.
Here are the steps:
1. Graph the first inequality: -2x-y1. We can rearrange the equation to get y>-2x-1. This means that the region above the line y=-2x-1 is the solution to the first inequality.
2. Graph the second inequality: 3x+y<6. We can rearrange the equation to get y<-3x+6. This means that the region below the line y=-3x+6 is the solution to the second inequality.
3. The solution to the system of inequalities is the region that satisfies both inequalities. This is the region above the line y=-2x-1 and below the line y=-3x+6.
4. To find the coordinates of the vertices of the solution region, we can find the intersection point of the two lines. Setting the two equations equal to each other, we get: -2x-1=-3x+6. Solving for x, we get x=7. Substituting x=7 into one of the equations, we get y=-3(7)+6=-15. So the intersection point is (7,-15).
5. The solution region is the triangular region with vertices at (7,-15), (0,-1), and (2,0).
Therefore, the solution to the system of linear inequalities is the region with vertices at (7,-15), (0,-1), and (2,0).

The number of people who had turkey on their sandwiches is 475.
option A.
What is the number of people who had turkey on sandwiches?
Let's define the following;
A be the number of people who chose turkey,
B be the number of people who chose ham,
C be the number of people who chose both, and
D be the number of people who chose neither.
From the problem statement, we know that:
D = 75 (75 attendees chose neither)
C = 250 (250 attendees chose both)
B = 450 (450 attendees chose ham)
We want to find A (the number of attendees who chose turkey).
We can start by using the formula for the number of elements in the union of two sets:
|A U B| = |A| + |B| - |A n B|
where;
|A| and |B| denotes the number of elements in set A, set B and A n B denotes the intersection of sets A and B.Applying this formula to the problem, we get:
750 - D = A + B - C
750 - 75 = A + 450 - 250
675 = A + 200
A = 475
Therefore, 475 attendees chose turkey on their sandwiches. The answer is (A) 475.

4500 dollars is placed in an account with an annual interest rate of 7%. To the nearest tenth of a year, how long will it take for the account value to reach 10800 dollars?
It will take 13 years for the account value to reach $10,800.
How long will it take to grow to $10,800?Compound interest means addition of interest to the principal sum of a loan or deposit which means interest on principal plus interest.
We will use the formula for compound interest [tex]A = P(1 + r/n)^{nt}[/tex]
Given that
A = Final account value ($10,800)
P = Principal amount ($4,500)
r = Annual interest rate (7% or 0.07)
n = 1
t = ?
$10,800 = $4,500(1 + 0.07/1)^(1*t)
Dividing by $4,500:
2.4 = (1.07)^t
Taking the logarithm of sides:
log(2.4) = log((1.07)^t)
Using logarithmic identity log(a^b) = b*log(a):
log(2.4) = t*log(1.07)

The correct option is B, The area of the figure will be the sum of the area of the rectangle and half the area of the circle is 220 cm².
The rectangle has a length of 22 cm and a width of 10 cm, so its area is:
A_rectangle = length × width = 22 cm × 10 cm = 220 cm²
A rectangle is a four-sided polygon with opposite sides parallel and equal in length. The area of a rectangle is the measure of the space that it occupies and is given by the product of its length and width.
To find the area of a rectangle, one needs to multiply the length of the rectangle by its width. For example, if the length of the rectangle is 5 meters and its width is 3 meters, the area would be 15 square meters. This is because 5 multiplied by 3 is equal to 15. In general, the formula for the area of a rectangle is A = lw, where A is the area, l is the length, and w is the width. The units of the area will depend on the units of the length and width.

the values of a that satisfy the inequality |a|≤5 are those that satisfy both a ≤ 5 and a ≥ -5. This is why the expression equivalent to |a|≤5 is a ≥ –5 and a ≤ 5.
What is expression ?
In mathematics, an expression is a combination of numbers, variables, and operators that can be evaluated to produce a value. It can be as simple as a single number or variable, or as complex as a long sequence of operations involving multiple variables and operators.
The expression |a|≤5 means that the absolute value of a is less than or equal to 5. The absolute value of a number is its distance from zero on the number line, regardless of whether the number is positive or negative.
So, if |a|≤5, then a must be between -5 and 5, including both.
To see why this is true, consider two cases:
If a is greater than or equal to zero, then |a| = a, and so we have a ≤ 5.
If a is less than zero, then |a| = -a, and so we have -a ≤ 5, which is equivalent to a ≥ -5.
Therefore, the values of a that satisfy the inequality |a|≤5 are those that satisfy both a ≤ 5 and a ≥ -5. This is why the expression equivalent to |a|≤5 is a ≥ –5 and a ≤ 5.

(14, 10, 14) = 1(3, 1, 7) + 2(1, -1, 6) + 1(7, 5, 5)
= (3, 1, 7) + (2, -2, 12) + (7, 5, 5)
= (14, 10, 14)
So, the linear combination is 1u + 2v + 1w.

Use the functisn value to find the indicoted trigancmetric value in the specified quodrant. Futietion value quadrant. Trigonomstric Value
cosich (C)= 3
2
coc(O)
chic(a)
The indicated trigonometric values in the specified quadrant are sec(O) = 1/3, sin(O) = sqrt(-8), and csc(O) = 1/sqrt(-8).
To find the indicated trigonometric value in the specified quadrant using the function value, we need to use the relationships between the different trigonometric functions. The given function value is cosich (C) = 3 in quadrant 2.
First, we can use the relationship between cosine and secant to find the value of secant. The relationship is:
sec(O) = 1/cos(O)
Since cosich (C) = 3, we can substitute this value into the equation and solve for sec(O):
sec(O) = 1/3
Next, we can use the relationship between cosine and sine to find the value of sine. The relationship is:
sin^2(O) + cos^2(O) = 1
Substituting the value of cosich (C) = 3 into the equation, we get:
sin^2(O) + 3^2 = 1
Solving for sin^2(O), we get:
sin^2(O) = 1 - 9 = -8
Taking the square root of both sides, we get:
sin(O) = sqrt(-8)
Since we are in quadrant 2, the value of sine will be positive. Therefore, the value of sin(O) is sqrt(-8).
Finally, we can use the relationship between sine and cosecant to find the value of cosecant. The relationship is:
csc(O) = 1/sin(O)
Substituting the value of sin(O) = sqrt(-8) into the equation, we get:
csc(O) = 1/sqrt(-8)
Therefore, the value of csc(O) is 1/sqrt(-8).
In conclusion, the indicated trigonometric values in the specified quadrant are sec(O) = 1/3, sin(O) = sqrt(-8), and csc(O) = 1/sqrt(-8).

Given that the lines with arrows in figure 10. 29 are parallel , determine the sum of the angles a+b+c+d+e without measuring the angles. Explain your reasoning
The parallel line pairs, AB and BC ; CE and AD are present in the above figure. The sum of the angles a+b+c+d+e without measuring the angles is equals to the 180°.
We have the lines, AB and BC with arrows in above figure are parallel and we determine the sum of the angles a + b + c + d + e, without measuring the angles. Both of lines, AB and BC intersects each other at point B. Similarly, AD and CE lines also intersect. Properties of parallel lines are
Corresponding angles are equal.Vertically opposite angles are equal.Alternate interior angles are equal.Alternate exterior angles are equal.Measure of angle, ECD = d
Measure of angle, CED = c
Measure of angle, ADE = b
Measure of angle, DAE = e
Measure of angle CBA = a ( corresponding angles)
Now, measure of angle ACE, ∠ACE= ∠CED = c ( alternating angles)
Similarly, ∠CAE = ∠CDE = e (alternating angles)
Now, measure of angle ACB = measure of angle BCE + measure of angle ACE
= c + d
Measure of angle CAB = measure of angle CAD + measure of angle DAB
= e + b
Sum of interior angles of a triangle is equals to the 180°. So, ∠ACB + ∠ABC + ∠BAC = 180°
=> c + d + e + b + a = 180°
Hence, required sum of angles is 180°.
