Answer:
D,
Step-by-step explanation:
the volume of a sphere is 4/3πr^3
-2y-4=4(y-1)
Always remove the pararentheses as your first step.
-2y-4 = 4y - 4
Combine like terms.
-2y - 4y = 4 - 4
-6y = 0
Divide both sides by -6 to find y.
-6y/-6 = 0/-6
y = 0
Done
Answer:
(x-2) (x+8)
Step-by-step explanation:
Answer:
x = -1/2
Step-by-step explanation:
multiply the -4 to all in parentheses
-4(3-2x) +2x =2x -8
-12+8x +2x =2x-8
isolate x by moving whole numbers to other side of equal sign and x to the other side
8x +2x -2x = -8+12
8x = -4
/8
divide by 8 to isolate x
x= -4/8
simplify
x= -1/2
