Question

Solve the inequality:

3z−1≤−7

Select one:

z≥2

z≥−2

z≤−2

z≤2

Answer 1

`z \leqslant - 2`

Step-by-step explanation:

1) Add 1 to both sides.

`3z \leqslant - 7 + 1`

2) Simplify -7 + 1 to -6.

`3z \leqslant - 6`

3) Divide both sides by 3.

`z \leqslant - (6)/(3)`

4) Simplify 6/3 to 2.

`z \leqslant - 2`

Therefor, the answer is Option C.

Answer 2

Answer:

z ≤ -2

Step-by-step explanation:

3z − 1 ≤ -7

3z ≤ -6

z ≤ -2
