<h2>Answer:</h2>

The solution to the inequality 5.25 – b ≥ 6.5 is:

                      b ≤ -1.25

i.e. in interval form it is:  (-∞,-1.25]

<h2>Step-by-step explanation:</h2>

We are given a inequality with a equality sign in terms of single variable b as follows:

                 5.25 – b ≥ 6.5

on subtracting both side by 5.25 we get:

          -b ≥ 6.5-5.25

  ⇒    -b ≥ 1.25

on multiplying both side by -1 we get:

                   b ≤ -1.25 or in interval form it is: (-∞,-1.25]

( As we know that on multiplying by a negative number the sign of the inequality get interchanged )

Find the numerical values of -3|x|+2x-1 if x=-5. PLSSSS HELP
Kisachek [45]

Answer:

26

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
