You start out with 3*-2+2y=10
Simplify and you get 2y-6=10
Add 6 to both sides. 2y=16

Solve the inequality.
Dovator [93]

The option c) x < -24 represents the solution set of the given inequality.

<u>Step-by-step explanation</u>:

The given inequality is −1/4x−12 > −6

<u>To find the solution set :</u>

Keep the x term on one side and constants on other side of the inequality.

-1/4x > -6+12

-1/4x > 6

-x > (6\times4)

-x > 24

Multiply both sides with -1 to remove the negative sign of x.

While multiplying or dividing a negative number in an equality, the inequality sign must be flipped.

⇒ x < -24

1/4 k = 3 (-1/4 k + 3)
Vladimir [108]

Simplify 1/4k to k/4

k/4 = 3(-k/4 + 3)

Regroup terms

k/4 = 3(3 - k/4)

Multiply both sides by 4

k = 12(3 - k/4)

Expand

k = 36 - 3k

Add 3k to both sides

k + 3k = 36

Simplify k + 3k to 4k

4k = 36

Divide both sides by 4

k = 36/4

Simplify 36/4 to 9

<u>k = 9</u>
