Answer 1

Answer:

Option E.

Step-by-step explanation:

The given inequalities are

$-15x+4\leq 109$

$-6x+70>-2$

We need to find the solution of given compound inequality.

Solve each inequality separately.

Solve first inequality:

$-15x+4\leq 109$

Subtract 4 from both sides.

$-15x\leq 109-4$

$-15x\leq 105$

Divide both sides by -15. If we multiply or divide an inequality by a negative number, then the sign of inequality is changed.

$x\geq -7$              .... (1)

Solve second inequality:

$-6x+70>-2$

Subtract 70 from both sides.

$-6x>-2-70$

$-6x>-72$

Divide both sides by -6.

$x<12$                   .... (2)

Form (1) and (2) we get

$x\geq -7\text{ or }x<12=\text{All real numbers}$

Therefore, the correct option is E.
