2x + y = 17
To solve for y, subtract 2x from both sides;
y = 17 - 2xTo solve for x, subtract y from both sides;
2x = 17 - y
Divide both sides by 2;

The number would be .5 I'm pretty sure
Answer:
= 192 pi units ^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
The radius is 8 and the height is 3
V = pi ( 8)^2 ( 3)
= 192 pi units ^3
Answer: y=2x+1 is parallel & y=-2x+5 is perpendicular
