How do you solve f (x)=-3 (x+2)+2
Allushta [10]

Answer:

−1/3y+−4/3

Step-by-step explanation:

We need to solve for x.

How? Easy! :D

Step one: Flip the equation. (In class we call it the 'flip-flop'.) When you do this, you should have your equation look like this:

−3x−4=y

Step two: Add 4 to both sides of the equation. When you do this step, your problem should look like this:

−3x−4+4=y+4

−3x=y+4

Step three: Divide both sides by -3.

-3x/-3 = y+4/-3.

Step four: Wrap-up. What the answer is.

x = -1/3y + -4/3

Final step: OUR ANSWER!

x = -1/3 + -4/3

Hope this helped! :D

Which ordered pair is not a solution of y = 2x + 1?
Dmitrij [34]

Answer:

(-1,1)

Step-by-step explanation:

All you have to do is plug it in the equation:

      (x,y)

For (-1,1)

1=2(-1)+1

Simplify:

1=-1 but you know that 1≠-1 so (-1,1) is not it

For (3,7)

7=2(3)+1

Simplify:

7=7

For (-3,-5)

-5=2(-3)+1

-5=-5

Simplify:

For (0,1)

1=2(0)+1

1=1
