Answer:
the slope is -1/2 and the y-intercept is -4
Step-by-step explanation:
The original formula is y=mx+b. m is the slope of the graph and b is the y-intercept. You just plug in the numbers to the original formula to get the formula for the graph. The slope is always the number that is right next to the x, or the number which is multiplied by the x. The y-intercept is always the number that is not by x.
The original price of the item will be $ 480.When there is 75% off on the original price.
<h3>What is the percentage?</h3>
The quantity of anything is stated as though it were a fraction of a hundred. A fraction of 100 can be used to express the ratio.
The right question is
"Joyce saved $120 on an item that was 75 % off. What was the original price?"
Given data;
% off = 75
Amount saved $120
Let the original price of the item is x
75 % of x + $120 = x
0.75x+ 120 =x
0.25 x =120
x=120/0.25
x=480
Hence, the original price of the item will be $ 480.

Answer:
-9
Step-by-step explanation:
This is just -3 * 3
=-9
Area of a circle = pi * r^2
Radius (r) = ½ * diameter
½ * 10 = 5
A= pi * 5^2
25 * pi = 78.54 sq inches
10.99 / 78.54 = about 14 cents per sq in (13.99)
