Will give brainliest i need with this right now show work

Hello from MrBillDoesMath!

 The cylinder on the left has 4 times the volume of the cylinder on the right.

Discussion.

The volume of a cylinder of height "h" and radius "r" is given by

PI * r^2 * h                     (r^2 signifies r squared)

(Think of this formula as the area of the circle or radius r multiplied by the height the circle is pushed "up" to create the cylinder)

The volume of the cylinder on the left is:    Pi * 4^2 * h =   16 Pi *h

The volume of the cylinder on the right is: Pi * 2^2 * h =   4 Pi *h

As 16/4 = 4, the cylinder on the left has 4 times the volume of the one on the right.

Thank you,  

MrB

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
