Step-by-step explanation:
Y=-2x+7 That is the equation written in y=mx+b formula
They are not proportional because they do not have a constant ratio. If the data on the graph shows a curved line, it is not constant and is not proportional.
Answer:
y=5cosx
Step-by-step explanation:just took the test.
S + c = 79.10
s = 3.50 + 3c
3.50 + 3c + c = 79.10
3c + c = 79.10 - 3.50
4c = 75.60
c = 75.60/4
c = 18.90 <==== amount spent on coffee
s = 3.50 + 3(18.90)
s = 3.50 + 56.70
s = 60.20 <=== amount spent on soy lattes
