A chemical engineer is trying to increase the amount of the useful product in a reaction. She performs the reaction with her new equipment 10 times
and gets the following amounts of the useful product: What proportion of the reactions were above the 48 grams threshold?

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
