I could use a little help with this one. i'm rusty.
-3(x+2)-7 = 5x + 7

-3(x+2)-7 = 5x + 7

-3x - 6 - 7 = 5x + 7

-3x - 13 = 5x + 7

-20 = 8x

x = -2.5

Exact form = x=-5/2

Decimal form = x=-2.5

Mixed number form = x=-2 1/2

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

-3(x+2)-7 = 5x + 7

-3x - 6 - 7 = 5x + 7

-3x - 13 = 5x + 7

-20 = 8x

  Divide both sides by 8 to get x by itself

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

ummm seems that u didnt post the attachement !
