slope-intercept form: y = mx + c, where m is the gradient and c is the y-intercept!!!
x - 26y = 52
-26y = -x + 52
y = x/26 - 2
What is the slope of the line that passes through the points (-9,5) and (-17,5)? Write your answer in simplest form.
Answer:
0
Step-by-step explanation:
Without solving anything, we can tell that the line that crosses these points is a horizontal line because both of the y-coordinates are the same. This tells us that the slope of the line is 0.
To prove this, we can find the slope of the line by plugging the two points,[tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex], into the equation [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]\frac{y_2-y_1}{x_2-x_1}\\\frac{5-5}{-17-(-9)}\\= \frac{0}{-17+9)}\\= \frac{0}{-8}\\= 0[/tex]
Therefore, the slope of the line that passes through the points (-9,5) and (-17,5) is 0.

Approximately how many years will it take $3000 to double if it is invested in an account that pays 3%
compounded monthly? Round your answer to the nearest whole year.
Answer:
24 years
Step-by-step explanation:
Total = start*(1 + interest rate / amount of times compounded per month)^(years*amount of compounds per year)
6000 = 3000*(1+0.03/4)^(4x)
6000 = 3000* ((403/400)^4)^x
2 = ((403/400)^4)^x
x = log base-((403/400)^4) of 2 = x
x = 23.19
rounding down 23 years (but you probably want a year over that to get at least 6000, so 24)
Which shape has at least one one pair of perpendicular sides?
Answer:
the square
Step-by-step explanation:
perpendicular = 90 degrees
Square (Option 1) has at least one pair of perpendicular sides
What is perpendicular?"Perpendicular means two lines, or sides, that meet at a right angle. A right angle is the measurement of 90 degrees."
What are perpendicular sides?"Perpendicular sides are at a 90-degree angle. Since they are so common, there is a special symbol to signify the sides are perpendicular without measuring."
Option 1
Squares are made up of two sets of parallel line segments, and their four 90° angles mean that those segments also happen to be perpendicular to one another.
Option 2
A parallelogram is a special kind of quadrilateral that is formed by parallel lines. The angle between the adjacent sides of a parallelogram may vary but the opposite sides need to be parallel for it to be a parallelogram.
Option 3
There are three angles in a triangle. These angles are formed by two sides of the triangle, which meets at a common point, known as the vertex. The sum of all three interior angles is equal to 180 degrees.
Option 4
A trapezoid is a quadrilateral with exactly one pair of parallel sides. Isosceles trapezoids have two sides which are equal sized and have the same angles between themselves and the bases.
Hence, Square (Option 1) has at least one pair of perpendicular sides

Paula knows the total cost for 100 students will be $750, and the cost total cost for 150 students is $1050. What is the caterer’s fixed cost and the rate per student served?
Step-by-step explanation:
the price charged for 100 students reflects the cost per student that applies to the order as a whole.
100 * 6 = $600, so the fixed cost is 750-600 = 150.
...
We can check this by substituting in the other equation.
Does 150*6 + 150 = 1050?
150*6=900
900+150 = 1050.
Yes, it does
...
We can express this relationship by the equation:
y = mx + b
where
y = total cost
m = $6 per student
x = number of students
b = fixed costs = 150
y = 6x + 150
The caterer’s fixed cost and the rate per student served is $6 and $150
How to choose what quantity to multiply the first equation?This method is actually called method of elimination to solve a system of linear equations.
We make one specific variable's coefficients of equal magnitude so that we can subtract or add the equations and eliminate that variable to make it easy to get the value of the other variable which will then help in getting the value of the first variable (if working in dual variable system).
If we have equations:
[tex]a_1x + b_1y = c_1\\a_2x + b_2y = c_2[/tex]
then, if we want to eliminate variable x, then we have to multiply equation 1 with
[tex]-\dfrac{a_2}{a_1}[/tex]
which will make coefficient of x in first equation as
[tex]a_1 \times - \dfrac{a_2}{a_1} = -a_1[/tex]
Then adding both equation will eliminate the variable x.
Given;
Cost of 100 students= $750
Cost of 150 students= %1050
Let the fixed cost of caterer be x
and the cost per student be y
x+100y=750...(1)
x+150y=1050...(2)
solving the above equations;
50y=300
y=6
x=750-600=150
The fixed cost is $150, while the per-student cost is $6.

Which equation represents the transformation of f(x)=|x| when effected by a vertical stretch of 3, a horizontal shift to the right 4 units, and a vertical shift up 2 units?
g(x)= 1/3 |x−4| + 2
g(x)= 1/3 |x+4| − 2
g(x)= 3 |x−4| + 2
g(x)= 3 |x+4| + 2
Answer:
b
c
Step-by-step explanation:
First question: x - 6 means there is a shift to the right.
Second Question: substitute the given values into the original equation for appropriate transformations.
Answer: 3 |x-4| + 2, because vertical stretch multiplies x, horizontal shifts are subtracted or added to x, and vertical shifts are added or subtracted to the entire function.
The movement of the curve in the graph is shifting of the curve in vertical or the horizontal direction.For the first function the graph horizontal shift of 6 units right and for the second function when it is vertical stretch of 3, a horizontal shift to the right 4 units, and a vertical shift up 2 units the transformation function is,
[tex]g(x)=3|x-4|+2[/tex]
Given-
The equation of the graph given in the problem is,
[tex]f(x)=\sqrt{x} [/tex]
Translation of the graphThe movement of the curve in the graph is shifting of the curve in vertical or the horizontal direction.
a) The equation of the graph when it is transferred is given as,[tex]g(x)=\sqrt{x-6} [/tex]
There is no change with the constant value. Thus the graph will not move in vertical direction. The change in variable of a unit result in the graph shift in horizontal direction.
As it shift -6 thus graph horizontal shift of 6 units right.
b) The given function is,[tex]f(x)=|x|[/tex]
Vertical stretch of 3 means multiply the function with unit 3.
[tex]g(x)=3|x|[/tex]
Horizontal shift to the right 4 units means the difference of 4 units in the variable,
[tex]g(x)=3|x-4|[/tex]
Vertical shifts up with 2 units means the addition of the constant 2.
[tex]g(x)=3|x-4|+2[/tex]
Hence, for the first function the graph horizontal shift of 6 units right and for the second function when it is vertical stretch of 3, a horizontal shift to the right 4 units, and a vertical shift up 2 units the transformation function is,

Answer:
40 m wide240 m perimeter₹80,000 cost to digStep-by-step explanation:
Given a land area of 3200 m² with a length of 80 m, you want the width, perimeter, and cost of digging at ₹25/m².
WidthThe formula for the area of a rectangle can be used to find the width of the plot.
A = LW . . . . . . area is the product of length and width
3200 m² = (80 m)W . . . . . fill in given values
40 m = W . . . . . . . . . . . . divide by the coefficient of W
The width of the plot is 40 m.
PerimeterThe perimeter can be found using the formula ...
P = 2(L +W)
Using the length and width we know, this is ...
P = 2(80 m +40 m) = 2(120 m)
P = 240 m
The perimeter of the plot is 240 m.
Digging costThe cost of digging will be the product of the number of square meters and the cost of digging each one:
digging cost = (3200 m²)×(₹25 /m²) = ₹80,000
The cost of digging the land is ₹80,000.

How to determine the distance between the points?The points are given as
(2.4, -5.4) and (9.2, -5.4)
The distance between the points is calculated as
d = √(x2 - x1)^2 + (y2 - y1)^2
Substitute the known values in the above equation
So, we have
d = √(9.2 - 2.4)^2 + (-5.4 + 5.4)^2
Evaluate the sum in the above equation
So, we have
d = √(9.2 - 2.4)^2 + (0)^2
Evaluate the difference in the above equation
So, we have
d = √(6.8)^2 + (0)^2
Evaluate the exponents in the above equation
So, we have
d = √46.24 + 0
Evaluate the sum in the above equation
So, we have
d = √46.24
Evaluate the exponents in the above equation
So, we have
