Answer:
rise = -3
run = 4
rise/run = -3/4
Step-by-step explanation:
See figure for visual
The rise/run ratio gives the slope of the line
Take any two points on the line. I chose A(x1 = 2, y1 = 3) and B(x2 = 6, y2 = 0) as shown in the graph
For these two points the rise is (y2 - y1) = 0 - 3 = -3
The corresponding run is (x2 - x1) = 6 - 2 = 4
rise/run = -3/4 which is the slope of the line. This line has a negative slope - as x increases, y decreases
Not sure if that's what they are looking for.

-7/5, 16, -1, 3.2, -6.5, 0, 3/4,
Answer:
Step-by-step explanation:
First, change the fractions into decimals, then use the knowledge of the number line system to know which is greater or smaller than who.
-7/5 -1.4
3/4 0.75
so the numbers are -1.4, 16, -1, 3.2, -6.5, 0, 0.75
from greatest to least:
= 16, 3.2, 0.75, 0, -1, -1.4, -6.5
There are 15 pieces of fruit in a bowl and 6 of them are apples. What percentage of the pieces of
fruit in the bowl are apples?
A. 0.06%
B. 40%
C. 6%
D. 0.4%
Answer:
40%.
Step-by-step explanation:
There are 6 / 15 apples out of the bowl.
6/15 = 2/5 = 0.4
So, 40% of the fruit in the bowl are apples.

Jeff is purchasing a car for $29,175 that will depreciate in value 7.5% each year.
Write a function to model the value P of the carafter t years,
If he decides to sell the car after 6 years, what will be the value of his car? Express your answer as a decimal rounded to the nearest hundredth.
Answer:
p= 18,275
Step-by-step explanation:
The function would be p=29,175(-0.925)^t. You would then substitute t for 6 and solve from there to get p=18,275.

Here's a graph of a linear function.
Write the
equation that describes that function.
Express it in slope-intercept form.
Answer:
y = 1/2x + 3Step-by-step explanation:
As per graph, using the points (-6, 0) and (0, 3) we determine that:
the y-intercept is 3 and the slope is m = (3-0)/(0 - (-6)) = /3/6 = 1/2So the equation is:
y = mx + by = 1/2x + 3It took Mrs. Harpole 35 minutes to grade

a norman window has the shape of a rectangle surmounted by a semicircle. if the perimeter of the window is 25 feet, express the area of the window as a function of the width (across the base) of the window.
The area of the window is [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]
The shape of the Norman window is described as a rectangle surmounted by a semicircle.
Let 'x' be the width of the window.
Then this width corresponds to the diameter of the semicircle.
That is, radius of the semicircle = x/2
Now given the perimeter of the whole window = 25 ft
This perimeter is equal to the sum of 3 sides of the rectangle and the perimeter of the semicircle.
Perimeter of the semicircle = [tex]\frac{2\pi r}{2} = \frac{\pi x}{2}[/tex] , where r is the radius of the semicircle.
Now let 'y' be the length of the window.
Then sum of three sides of the window = 2y + x
So 2y + x + [tex]\frac{\pi x}{2}[/tex] = 25
Therefore, [tex]y =( 25 - x - \frac{\pi x}{2} ) / 2[/tex]
Area of the window = Area of the semicircle + Area of the rectangle =
[tex]\frac{\pi x^2}{8} +xy = \frac{\pi x^2}{8} + x( 25 - x - \frac{\pi x}{2} ) / 2\\ = \frac{\pi x^2}{8} + (25x - x^2 - \frac{\pi x^2}{2} ) / 2[/tex]
So Area of the window = [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]

A system of two linear equations with two variables is
shown below.
2x + y = 7
3x - 4y = 5
Which answer is the solution to the system of linear
equations?
Answer:
:/
Step-by-step explanation:
Answer:
x = 3, y = 1
Step-by-step explanation:
Given the 2 equations
2x + y = 7 → (1)
3x - 4y = 5 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the y- term
8x + 4y = 28 → (3)
Add (2) and (3) term by term to eliminate y
11x = 33 ( divide both sides by 11 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 7
6 + y = 7 ( subtract 6 from both sides )
y = 1
solution is x = 3 and y = 1
