if you subtract 12 from my number and multiply the difference by -6 the result is -90 what is my number

your number is ‐15

hope its right

n must be 27

Step-by-step explanation:

Let this number be x.  Then -6(n - 12) = -90.

Dividing both sides by -6 yields n - 12 = 15.

Add 12 to both sides.

Then n must be 27.

Check:  subtract 12 from 27; this yields 15.  Now multiply this result by -6.  The result is -90, which was expected.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
