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

Answer 1

26

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`
