The required value of x is; x ≥ 0

The function, f(x) can be found by analyzing the data provided in the table as follows;

The first difference of the data in the Monthly cost column is; 35 - 33.75 = 33.75 - 32.5 = 32.5 - 31.25 = 31.25 - 30.00 = 1.25 = Constant

The (first) difference in the values in the Number of Songs Downloaded column is 1 (constant), therefore, the function is a linear function with a slope of 1.25

The value of the function which is the Monthly cost When the Number of Songs Downloaded is 0 is 30, therefore, the y-intercept is; c = 30

The function f(x) is therefore; f(x) = 1.25·x - 30

(14, 10, 14) = a(3, 1, 7) + b(1, -1, 6) + c(7, 5, 5)

This can be written as a system of equations:

14 = 3a + b + 7c

10 = a - b + 5c

14 = 7a + 6b + 5c

We can solve this system of equations using any method we prefer, such as substitution or elimination. One possible solution is:

a = 1

b = 2

c = 1

Therefore, the linear combination of u, v, and w that gives us (14, 10, 14) is:

(14, 10, 14) = 1(3, 1, 7) + 2(1, -1, 6) + 1(7, 5, 5)

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.

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.

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

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°

The coordinates of R′ for the dilation centered at P with scale factor 0.5 are R' (-1, -0.5).

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 0.5 centered at the point P (-3, -3) by using this mathematical expression:

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)

The sets of points that have a distance of 4 units between them are:

Point X and Point W

Point T and Point S

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.

What is a graph ?

Graph can be defined as visual representation of data using ordered pairs.

The graphs of y = 1/2x - 10 - 3 and y = 1/x have different shapes and behaviors.

The graph of y = 1/2x - 10 - 3 is a linear function with a slope of 1/2 and a y-intercept of -13. This means that the graph will have a constant slope of 1/2, and will be downward sloping from left to right. As x increases, y decreases at a steady rate.

On the other hand, the graph of y = 1/x is a non-linear function that is a hyperbola. This means that the graph will be curved and will have two branches, one in the first quadrant and the other in the third quadrant. The graph will approach the x and y-axes but will never touch them. The curve will be symmetric about the line y = x, which means that for every point (x, y) on the graph, there will be a corresponding point (y, x) on the graph.

Therefore, the graphs of y = 1/2x - 10 - 3 and y = 1/x are different in shape and behavior, and their only similarity is that they are both continuous functions.

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).

The triangles are similar thus option A. Yes, SSS

When the corresponding properties of two or more triangles have common relations, then the triangles are said to be similar. Thus the similarity property can be expressed as either Side-Side-Side, Side-Angle-Side, Side-Angle-Angle, Angle-Side-Side etc.

Though two or more triangles are said to be similar but not congruent.

Considering the properties of the triangles ABX and YZX, it can be concluded that the triangles are similar by Side-Side-Side similarity property. Therefore the appropriate option is A. Yes, SSS.

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.

Answer:

The percent decrease is 36%.

Step-by-step explanation:

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.
