A. (–∞, 2]
B. (–∞, 2)
C. (–∞, 6]
D. (–∞, 6)

Answer 1

The answer is C.

I hope this helps.

Answer 2

option C (-∞,6]

Explanation:

`5x - 10 \leq 20`

To solve the inequality we need to get x alone

To get x alone , add 10 on both sides

`5x - 10+10 \leq 20+10`

`5x \leq 30`

Divide both sides by 5

`x \leq 6`

for
`x \leq 6`, the solution is (-∞,6]
