Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
Answer:
0.0138888888889 or
1/72
Step-by-step explanation: The answer can be found in Desmos
•y-intercept is 20
•y-intercept represents how many glass bottles you need to earn $1.00 if you have 0 aluminum cans
•x-intercept is 50
•x-intercept represents how many aluminum cans you need to earn $1.00 if you have 0 glass bottles
A direct variation suggest that the value of x in the equation would greatly affect the value of y such that when x is increasing, y also increases and the other way around. The equation for a direct variation is that,
y = kx
Substituting the given values in the ordered pair,
5 = k(4) ; k = 5/4
