How can x2 = x2 + 2x + 9 be set up as a system of equations?

x = - 4.5

Step-by-step explanation:

The given expression is x² = x² + 2x + 9

we have solve the equation.

In this equation we will transfer like terms in one side of the equation.

x² - x² = 2x + 9

2x + 9 = 0

Now we subtract 9 from each side of the equation.

2x + 9 - 9 = 0 - 9

2x = -9

Now we will divide by 2 on each side of the equation.

2x/2 = -9/2

x = -4.5

step-by-step explanation:

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
