find the constant of proportionality for the graph and write in the form y = kx.
a) y =
1
6
x
b) y = 6x
c) y = 7x
d) y = 42x

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

okay then that is your answer you know that 4 bottlkes of water cost ten $ at the music festival
