What are the solutions to the absolute value inequality |x − 70| ≤ 3? Remember, the inequality can be written as −3 ≤ x − 70 ≤ 3

ikadub [295]

Answer:

solutions to the absolute value inequality is $67\leq x\leq 73$

Step-by-step explanation:

To find the solution of x absolute value of |x − 70| ≤ 3 will be written in the form of interval because the given fraction (x-70) is less than and equal to 3.

$-3\leq(x-70)\leq 3$

Now we add 70 on every part of the inequality.

$-3+70\leq (x-70)+70\leq 3+70$

$67\leq x\leq 73$

So the solution to the absolute value inequality is $67\leq x\leq 73$ .
