Answer:

Step-by-step explanation:

y(y+2)=y²-6

y²+2y=y²-6

2y=-6

y=-3

2[x-(1-3x)]=3(x+1)

2[x-1+3x]=3x+3

2(4x-1)=3x+3

8x-2=3x+3

8x-3x=3+2

5x=5

x=1

X^2 + x - 56 = 0<br> Solve for x

NISA [10]

Answer: x = 7 or x = -8

x² + x - 56 = 0

⇔ x² + 8x - 7x - 56 = 0

⇔ x(x + 8) - 7(x + 8) = 0

⇔ (x - 7)(x + 8) = 0

⇔ x - 7 = 0

or x + 8 = 0

⇔ x = 7 or x = -8

The graphs below have the same shape the equation of the red graph is f(x) =x^2. What is the equation of the blue graph?

daser333 [38]

Answer:

$G(x)=(x-6)^2$

which agrees with the answer D of your options

Step-by-step explanation:

Notice that the graph of G(x) has the initial graph shifted horizontally to the right in 6 units, therefore such horizontal shift is accomplished by subtracting the 6 units from the x-variable in the original expression:

$G(x)=(x-6)^2$
