I just finished my semester exam, and this was one of the questions. I guessed on this question because I had no clue of what the answer was, and lucky me, I got the question right :D

Hope this helps y'all with your test :)

Find the numerical values of -3|x|+2x-1 if x=-5. PLSSSS HELP

Kisachek [45]

Answer:

Step-by-step explanation:

Since x = -5, we can replace x with it's numerical -5, right? The problem tells you that x is equal to -5. So, just replace any x you see with -5.

So in this case,

$-3|x|+2x-1$

turns into:

$-3|(-5)|+2(-5)-1$

You can use a calculator or solve it by hand to see what the answer is.

$-3|(-5)|+2(-5)-1\\-3(5)+2(-5)-1\\-15+(-10)-1\\-25-1\\-26$
