C.-3
x=-3

3x-15/2=4x
multiply 2 on both sides
3x-15=8x
subtract 3x from both sides
-15=5x
divide 5 from both sides
-3=x

Answer:

D and yes

Step-by-step explanation:

$\frac{x}{4}$ + 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation

(4) $\frac{x}{4}$ + (4) 1 = (4) -3

x + 4 = -12 We solve this for x by subtracting 4 from both sides.

x = -16

Plug -7 into both equations and you will see that it is a solution

$\frac{x}{4}$ + 1 = -3

$\frac{-16}{4}$ + 1 = -3

-4 + 1 = -3

-3 = -3

x + 4 = =12

-16 + 4 = -12

-12 - -12

Which is the graph of LaTeX: y=x^2-4x+4y = x 2 − 4 x + 4?

Nat2105 [25]

Answer:

Step-by-step explanation:

Since we will be "completing the square" we will isolate the x2 and x terms ... so move the + 5 to the other side of the equal sign. y - 5 = 2x2 - 4x. We need a leading coefficient of 1 for completing the square ..
