Question

Select the graph for the solution of the open sentence. Click until the correct graph appears.

5|x| + 3 < 18

Answer 1

graph D

Explanation:

if x ≥ 0

5x + 3 < 18

5x < 18 - 3

5x < 15

x < 15/5

x < 3

0≤ x < 3

if x < 0

5(-x) < 18 - 3

- 5x < 15

x > 15/-5

x> -3

-3 < x < 0

final solution

-3 < x < 3
