Answer:
Step-by-step explanation:

First, on the right-hand side of the equation, let's distribute the
to each term in the parenthesis:

Now, let's move all the terms with an
to the left-hand side, and everything else to the right-hand side of the equation:

Let's combine like terms:

Finally, let's divide each side by
to get
by itself on the left-hand side of the equation:

Hmm question is a little confusing but fractions can be represented as division or a part of somthing, like 4 pieces of an 8 slice pizza, or you have 8 peices of pizza and you divide them by 4.

Answer:
(1, 2 )
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
C(1, - 2 ) → C'(1, 2 )
Answer:
y=2X+9
Step-by-step explanation:
y-7=2(x+1)
Distribute 2 through: y-7=2x+2
Add 7 over to the other side: y=2x+9
