Answer:

6. 7x + 3 = 3x; x = -3/4

7. x - 5 = 3x - 9; x = 2

Step-by-step explanation:

6. 7x + 3 = 3x

Subtract 3x from both sides.

7x + 3 - 3x = 3x - 3x

4x + 3 = 0

Subtract 3 from both sides.

4x + 3 - 3 = 0 - 3

4x = -3

Divide both sides by 4.

x = -3/4

7. x - 5 = 3x - 9

Subtract x from both sides.

x - 5 - x = 3x - 9 - x

-5 = 2x - 9

Add 9 to both sides.

-5 + 9 = 2x - 9 + 9

4 = 2x

Divide both sides by 2.

4/2 = (2/2) x

2 = x

Given the following absolute value function find the range. ƒ(x) = |x + 5| - 8

balandron [24]

The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0.

Tacking on "-8" to |x+5| leads to |x+5|-8

The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|
