barxatty [35]

Answer:

The answer to your question is $\frac{(x+1)^{2}(x - 23)}{(x-7)^{3}}$ , because the directions says to give the answer in factor form.

Step-by-step explanation:

$\frac{3(x+1)^{2}(x-7)^{2}- (x+1)^{3}(2)(x - 7)}{(x - 7)^{4}}$

Factor like terms (x - 7)(x + 1)²

$\frac{(x - 7)(x + 1)^{2}[3(x - 7) - 2(x + 1)}{(x - 7)^{4}}$

Simplify

$\frac{(x+1)^{2}[3(x - 7) - 2(x+1)]}{(x-7)^{3}}$

Expand

$\frac{(x+1)^{2}[3x - 21 -2x - 2]}{(x - 7)^{3}}$

Simplify

$\frac{(x + 1)^{2}(x - 23)}{(x - 7)^{3}}$

How to solve using Substitution or Elimination??? Help!! <br> y=3x-1<br><br> y=2x+2

aliina [53]

Answer:

Step-by-step explanation:

Since both equations equals y, then both equations equal each other.

3x - 1 = 2x + 2

Subtract 2x from both sides

x - 1 = 2

Add 1 to both sides

x = 3

Plug x = 3 into one equation(doesn't matter which)

y = 3x - 1

y = 3(3) - 1

y = 9 - 1

y = 8
