Answer:
Step-by-step explanation:
Proportional functions are of the form y=kx where k is the constant of proportionality.
k=y/x in this case
k=1008/3.5
k=288
Answer:
c,d
Step-by-step explanation:
because when u solve the problem those both have the same answer
Answer:
y = 2 and x = -3 the solutions of the equation
Answer:
95 city and 175 highway miles.
Step-by-step explanation:
The driver gets 20 mpg in city, and 28 mpg on the highway.
An equation that could be written is
20x+28y=270
This equation accounts for the distance traveled.
x+y=11
This equotion accounts for how many gallons were driven.
Multiply the bottom equation by 20, so you can solve the set of equations.
20x+28y=270
20x+20y=220
subtract them
8y=50
y=6.25
now plug this back into x+y=11
x+6.25=11
x=4.75
Now 4.75×20=95 city miles and 6.25×28=175 highway miles.
