What is the equation of the line in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
The equation of the line in the slope intercept form is y = (-1/2)x + 60
From the given graph,
Choose two points
(0, 60) and (40, 40)
The slope of the line the change in y coordinates with respect to the change in x coordinate of the function
The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Substitute the value in the equation
= [tex]\frac{40-60}{40-0}[/tex]
= -20/40
= -1/2
From the graph we can say that,
y intercept of the line = 60
The slope intercept form is
y = mx + b
where m is the slope of the line
b is the y intercept
y = (-1/2)x + 60
Hence, the equation of the line in the slope intercept form is y = (-1/2)x + 60

Rotate 90 counter clockwise around the origin and then reflect over the c-axis
Answers
In order to get the same outcomes as a form mirrored across the y-axis and turned counterclockwise, a shape can be reflected across the x-axis and then rotated 90 degrees in a clockwise manner around the origin. This suggests a similarity between these two transformative sequences.
What does mathematics mean by reflection?
A flip is the term used in geometry to describe a reflection. The mirror image of the form is a reflection. An image can reflect through a line known as the line of reflection. When all of the points in a figure are evenly spaced away from one another, the two figures are said to reflect each other.
(X, Y) > when a form is rotated 90 degrees counterclockwise (y, -x).
When the picture is reflected across the y-axis, (x, y) > (-x, y).
When those two transformations are used, it is the same as reflecting a shape across the line y = -x, where (x, y) > (-y, -x).
For instance: After being rotated 90 degrees clockwise and reflecting across the y-axis,
(2, 1) > (1, -2) > (-1, -2); and
(2, 1) > (-1, -2)
after being reflected across the y = -x line

At the bakery, they have 4 and a 1/8 pies for sale. They sell 1⁄4 of a pie for$5. How many pieces do they have to sell, and how much money will they make?
Answers
The number of pieces the bakery will sell is 16 and a half. The total amount of money they will make is $82.5.
What is the number of pieces of pies to be sold?To get the number of pieces of pies that they have to sell, we need to first determine how many 1/4 pies are in 4 and 8 pieces of bread. Going by that, we can see that:
1/4x of 4 = 16.
Also, 1/4x of 1/8 = 1/2.
So, the total number of pies that they have to sell is 16 and a half.
Now if 1/4 of a pie costs $5, then 4 1/8 will be equal to 33/8 × 5 ÷ 1/4.
This is equal to 165/8 × 4 = $82.5
So, the total amount of money that the bakery will make will be $82.5.

A swimming pool shaped like a rectangular prism has a volume of 124 cubic meters.
Rectangular prism is a three-dimensional shape that has 6 rectangle faces, 12 edges and 8 vertices.
Volume is defined as the amount of space that a three-dimensional shape occupies.
The volume of a rectangular prism can be calculated using the formula below.
V = l x w x h

Answers
The height of the tower is 9.24 feet. That is, the tower is 9.24 feet tall
Calculating the height of a towerFrom the question, we are to determine how tall the tower is
From the given information,
From a distance of 10 feet, the angle of elevation of the tower at a height 5 feet from the ground is 23 degrees.
Let x represent the length of the tower from a point 5 feet from the ground.
Thus,
The height of the tower will 5 + x feet
Now, we will determine x
Using SOH CAH TOA
tan 23° = x / 10
x = 10 × tan 23°
x = 4.24 feet
Height of the tower is 5 + x feet
Therefore,
Height of the tower = 5 + 4.24 feet
= 9.24 feet
