If the pool's being filled at a constant rate, then this rate is equal to the average rate, which would be
(2352 gal - 1372 gal) / (12 min - 7 min) = 980/5 gal/min = 196 gal/min
12 inches = 1 foot
144 square inches = 1 square foot
1250 square inches = 1250/144 = 8.68 square feet
Answer:
So the x-intercept is (9,0) and the y-intercept is (0,-3).
So I'm going to graph both points and connect them with a straight-edge.
Step-by-step explanation:
I would graph this using it's x- and y-intercepts.
To find the x-intercept, set y=0.
-3x+9(0)=-27
-3x+0=-27
-3x=-27
Divide both sides by -3:
x=9
To find the y-intercept, set x=0:
-3(0)+9y=-27
0 +9y=-27
9y=-27
Divide both sides by 9:
y=-3
So the x-intercept is (9,0) and the y-intercept is (0,-3).
So I'm going to graph both points and connect them with a straight-edge.
