Answer:

The graph in the attached figure ( is the third option)

Explanation:

we have the compound inequality


-18> -5x+2\geq -48

Divide the compound inequality in two inequalities


-18> -5x+2 -----> inequality A


-5x+2\geq -48 -----> inequality B

Step 1

Solve inequality A


-18> -5x+2


-18-2> -5x


-20> -5x

Multiply by -1 both sides


20<5x


4<x

Rewrite


x > 4

The solution of the inequality A is the interval ------>(4,∞)

Step 2

Solve the inequality B


-5x+2\geq -48


-5x\geq -48-2


-5x\geq -50

Multiply by -1 both sides


5x\leq 50


x\leq 10

The solution of the inequality B is the interval -----> (-∞,10]

therefore

The solution of the compound inequality is

(4,∞) ∩ (-∞,10]=(4,10]

All real numbers greater than 4 (open circle) an less than or equal to 10 (close circle)

The solution in the attached figure
