Which of the following represents the solution to the inequality 2 | 5 - 2x | - 3 ≤ 15 a. (-∞,-2) u (7,∞) b. (-∞,1.5) u (7.5,∞) c. [-2,7] d. [1.5,7.5]

Option C  

Step-by-step explanation:

we  have

Remember that

the absolute value has two solutions

Case positive

The solution of the case positive is the interval -------> [-2,∞)    

Case negative

The solution of the case negative is the interval -------> (-∞,7]

therefore

the solution is the interval

[-2,∞)  ∩ (-∞,7] =

the answer is d. (1.2, -4.7) on edgn

hope this !
