Solve the system for each variable.

2x + y + 4z = 3 and x + 2y = 2z - 3 and 4z + 3y = 0

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

pi x^2

step-by-step explanation:

pi times x squared

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
