What's the solution to |1x-12| < 15

1 answer:

5 0

Start with |1x - 12| < 15. Add 12 to both sides. Then |1x - 12 + 12| < 15 + 12

Simplifying, |x| < 27. Then the two solutions are x < 27 and x > -27. In words, the solution set is the set of all x greater than -27 and less than +27.

What do the letters I and P and R mean in "IPRT"?

cupoosta [38]

So P stands for principle which is the amount of the original investment, R stands for rate which is the percent but must be turned into a decimal, T stands for time for example if the time was in a certain amount of months then you plug that in with x/12, and lastly I stands for interest which is the original investment outcome ^_^
