Siana wrote these equations to help solve a number riddle .y= x-20 and x+y=84 What does Y equals X -20 tell you about the relationship between X and y .

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
