What is the solution to the equation below?
12345 [234]

Answer:

C  x=6

Step-by-step explanation:

sqrt(x+3) = x-3

Square each side

(sqrt(x+3))^2 = (x-3)^2

x+3 = (x-3)^2

x+3 = (x-3)(x-3)

FOIL

x+3 = x^2 -3x-3x+9

Combine like terms

x+3 = x^2 -6x+9

Subtract x from each side

x-x+3 = x^2 -6x-x +9

3 =  x^2 -7x +9

Subtract 3 from each side

3-3 =  x^2 -7x +9-3

0 = x^2 -7x+6

Factor

0 = (x-6)(x-1)

Using the zero product property

x-6=0   x-1 =0

x=6  x=1

Since we squared we need to check for extraneous solutions

x=1

sqrt(1+3) = 1-3

sqrt(4) = -2

2=-2

False

Extraneous

x=6

sqrt(6+3) = 6-3

sqrt(9) = 3

3=3

True   solutions

I need help with this math problem. If you can please give me an explanation.​
Serhud [2]

Answer:

see explanation

Step-by-step explanation:

Calculate the values of y by substituting the values of x into y = - 6x + 2

x = - 5 → y = - 6(- 5) + 2 = 30 + 2 = 32

x = - 1 → y = - 6(- 1) + 2 = 6 + 2 = 8

x = 0 → y = - 6(0) + 2 = 0 + 2 = 2

x = 1 → y = - 6(1) + 2 = - 6 + 2 = - 4

Thus

  x      y

 - 5    32

 - 1       8

   0      2

    1      - 4
