Which relation is not a function?
A. y=2|x|+3
B. y=-5(3.2)^x
C. 3x^2 + 3y^2= 20
D. 4x^2 + 3y^2= 9

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
