Answer:

-1

Step-by-step explanation:

This is the slope because x is the slope, and if there is no number in front of x then x is 1. There is also a negative in front of x which means the answer is -1.

Three times the square of the difference of x and 6 is 12

Elis [28]

Answer:

Equation: $3(x-6)^2=12$

Solutions: $x=4\text{ or }x=8$

Step-by-step explanation:

Unknown variable $= x$

Difference of x and 6 $= x - 6$

Square of the difference of x and 6 $=(x-6)^2$

Three times the square of the difference of x and 6 $=3(x-6)^2$

Three times the square of the difference of x and 6 is 12, then

$3(x-6)^2=12$

Divide this equation by 3:

$(x-6)^2 =4$

Now

$x-6=2\text{ or }x-6=-2\\ \\x=2+6\text{ or }x=-2+6\\ \\x=8\text{ or }x=4$
