Question

Which identifies all the integer solutions of |x| = 17?



A.


–17 only


B.


–17 and 17


C.
0 only


D.
17 only

I am so confused on this one.

Answer 1

Well this |x| is a modulus function, so if you put in any value of x inside | | you will get the positive value of x

Answer 2

It would be B because if you plug in -17 or 17 into x, it equals to 17. That's what the absolute symbols are those two vertical lines on the sides of x. It doesn't matter whether x is positive or negative, the final answer is always positive.

Answer 3

so |9| will give you 9 and |-9| will also give you 9

Answer 4

\(\bf |x| = 17\implies
\begin{cases}
+(x) = 17\\ \quad \\
\bf -(x) = 17
\end{cases}\)

solve for "x" in each scenario, you'd get 2 values for "x"

Answer 5

Thank you very much. Again haha

Math is my worst subject.

I fail miserably at it, as you can probably tell.

But thanksss!
