Question

PLS HELP, DUE TOMORROW!

select all equations that are equivalent to an equation that expresses y as a function of x
A: 3x-4y=-2
B: x-y⁴=0
C: x²-3y=0
D: lxl + lyl = 2
i have no clue what to look for here, if you could help that would be greatly appreciated!

Answer 1

Explanation:

A: 3x-4y=-2

3x=-2+4y

x =(-2+4y)/3

B: x-y⁴=0

x=y⁴

C: x²-3y=0

x²=3y

x=±√3y

D: |x| + |y| =2

x + y= 2

x =2-y
