Answer:

x= -54

Step-by-step explanation:

distribution- -8x-36+3x=6-4x+12

add like terms- -5x-36=-4x+18

get x alone -5x=-4x+54. added 36 to both sides

add 4x to both sides -x=54

divide by -1. x= -54

Answer:

x = -54

Step-by-step explanation:

6 - 4(x - 3) <em>=</em> 6 - 4x + 12 (4 times x, 4 times -3) <em>=</em> -4x + 18 (12 + 6).

-4(2x + 9) + 3x <em>=</em> -8x (-4 x 2x) - 36 (-4 x 9) + 3x <em>=</em> -5x (-8x + 3x) - 36.

-5x - 36 <em>=</em> -4 + 18

     +36         +36

-5x (-36 + 36 = 0) <em>= </em>-4x + 54 (18 + 36)

+4x                          +4x

-x = 54 (-4x + 4x = 0)

÷1   ÷1

x = -54

1/3 of the dimensions means to divide the dimensions by 3. This is to figure out what 1/3 of the dimensions are.
Our length is 6, and our width is 9.
Let's divide our length first.
6/3 = 2.
Our length with 1/3 of it's original dimensions is 2.
Let's divide our width now.
9/3 = 3.
Our width with 1/3 of it's original dimensions is 3.
Our dimensions are 2 by 3.
Your answer is A.) 2 in. by 3 in.

Find the inverse of g(x)=1/3x - 7 and then find its domain and range if you can show steps that would be gladly appreciated than
Schach [20]

Answer:

g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.

Step-by-step explanation:

Let y = 1/3 x - 7

1/3 x = y + 7

Multiply both sides by 3:

x = 3(y + 7)

So the inverse of g(x) = g-1(x) = 3(x + 7).

Domain is All Real values of x.

Range is All Real values of the function.
