So you want to solve for x?
It would be nice if this would easily factor:
(-4x + 5)(2x +1) = 0 This will not work!
So you need to use the quadratic formula:
a = -8, b = 4, c = 5

x = (-4 +/-

)/2(-8)
= (-4 +/-

)/-16
= (-4 +

)/-16
= 1/4 -

/4
Answer:Remember, the formula for slope is (y2 - y1) / (x2 - x1).
Step-by-step explanation:
Answer:
4
step by step if she has 7 cups and already put in 3
7-3=4
I would say it represents the volume function evaluated at r=5/7, or
V(5/7)=(4/3)π(5/7)² = 2.13714
