Question

Aye yo help me plz!

1.) Which of the following equations is not a linear equation?
A) y = -4
B)X 3 = 1
C) 2x -4y =1
D) y= X - 2

2.) Find the value of y that makes the equation y= -x + 5 true, when x =-4

A.) -1
B.) 2
C.) 1
D.) 9

3.) Find the value of y that makes the equation y= x + 1/4 true, when x = - 1/4.

A.) -4
B.) 0
C.) 1
D.) 4​

Answer 1

1) B

2) D

3) B

Explanation:

For question 1:

Assuming that option B is
`x^3=1`, it is not a linear function.

Linear functions have equations that do not have exponents.

For question 2:

`y=-(-4)+5\\\\y=4+5\\\\\boxed{y=9}`

The option is D.

For question 3:

`y=x+(1)/(4)\\\\ y=-(1)/(4)+(1)/(4)\\\\ \boxed{y=0}`

The option is B.

Hope this helps.
