What two numbers add up to 5 but multiply to -3? ​

32

step-by-step explanation:

these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.

We know on the regular cosine graph, it decreases from 0 to pi. so, we need to set 0 as y.0 = 4 cos(2x-pi)0 = cos(2x-pi)2x-pi = pix = piwe already know the answer, but do pi on your own!
