First you want to get h alone so you divide 2<span>π</span>r by s so your answer would be
h=S/2πr
The game costs 25 dollars. If 6/5 = 30 then 5/5 would be 25
Sub x=-5+2y
2(-5+2y)+4y=14
y=3
Answer: y = 1/2 or y = -1/2
Step-by-step explanation:
First move the 1 to the side with the 0
-4y^2 = -1 // -1 because when you move a number to the other side of the equation you have to multiply -1
Then divide by -4 on each side
y^2 = 1/4
square root each side
|y| = 1/2 // sq rt y^2 becomes an absolute value because when you square root a square it automatically becomes an absolute value
so the answer would be y = 1/2 or -1/2
to check just put it into the equation as y. Both work.
