Answer:

The value of x is 9.

Step-by-step explanation:

Given equation,

(x+2)^2=a

If x = 1 is the solution of this equation,

Then it will satisfy the equation,

\implies (1+2)^2=a

\implies (3)^2=a

\implies a = 9

Hence, the value of x is 9 if x = 1 is the solution of the given equation.

I really need help!!! It would mean a lot if someone could help me.
Rudiy27

The y answers would be 11, 8, 5, 2, -1.

To find these parts of the table, we simply put the x value in for x and solve for y. The first two are done for you below.

WHEN x = -2

y = -3x + 5

y = -3(-2) + 5

y = 6 + 5

y = 11

WHEN x = -1

y = -3x + 5

y = -3(-1) + 5

y = 3 + 5

y = 8

PLEASE HELP!!!
tatyana61 [14]

Answer: The equation is y= -2x -4

Step-by-step explanation:

The slope intercept form is like y=mx+b so we know the slope which is m but we just need to find the y intercept.

and we will use the given coordinates to find the y intercept by putting in the x and y coordinates into the formula y=mx + b

-6= -2(1) + b

-6= -2 + b

+2  +2

b= -4
