That would be D
the first 3 = -12x + 24
bur D = -12x - 24
A proportional graph is a straight line that goes through the origin while a non-proportional graph is a straight line that doesn't go through the origin.
y = mx + b
the b represents the y-intercept, so -3 is the y-intercept in the equation y = 3x -3
therefore, the line doesn't go through the origin and is a non-proportional equation
Answer:
its function a because im doing the same thing ur doing rn so what i got on that question was a because it would fit in with the formula the most
Step-by-step explanation:
The length of the fencing is 62.4 feet.
The width of the fencing is 17.6 feet.
Given,
The measurement of the Christmas garland = 160 feet
The width of the fencing = w
The length of the fencing, l = 4w - 8
We have to find the length and width of the fencing.
Here,
Perimeter can be taken as 160. Because garland will cover the entire fencing.
Perimeter = 2(l + w)
160 = 2(4w - 8 + w)
160 = 2(5w - 8)
160/2 = 5w - 8
80 + 8 = 5w
88/5 = w
width = 17.6 feet
Now,
l = 4w - 8
l = 4 × 17.6 - 8
l = 70.4 - 8
length = 62.4 feet
That is,
The length of the fencing is 62.4 feet.
The width of the fencing is 17.6 feet.

Answer:
The area is approximately 453 ft²
Step-by-step explanation:
Area of a circle = 
If 
= 22/7, and r = 12 ft
Area = (22/7)×12²
= 3.143*144
= 452.592 ft²
≈ 453 ft²
