B=-3
because you divide 27 by -9 to get y by its self
The answer is 4/7. see it from the multiple of 3...3*4 =12 and 3*7= 21. So this is the answer: 4/7.
Answer:
(0,1/5) and (1/9,0)
Step-by-step explanation:
3/5x +1/3y=1/15
To find intercepts, plug in 0
y-intercept: 3/5(0) + 1/3y=1/15
y=1/15*3 = 3/15 = 1/5 or 0.2
x-intercept: 3/5x + 1/3(0) = 1/15
3x=1/15*5/3
x=5/45= 1/9
The discount is 50-14 = $36
% discount = (36/50)*100 = 72%
