Which equations are in standard form? Check all that apply Y=2x+5
2x+3y=-6
-4x+3y=12
Y=3/2x-9
1/2x+3=6
x-y=5
5x+3y=1/2

if u need help go to math  way .

Step-by-step explanation:

math   way  is a good way to get the steps and answer to ur problem.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
