Solve this system of equations, then determine what y equals. x + 5y= 7
2x + 4y = -4
O y=
y=-18
Oy=3
y=3
y=8
Oy=
y=-8

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

x+4 would be the answer
