Answer:

Step-by-step explanation:
The equation of 2 quantities in direct proportion is
y = kx ← k is the constant of proportionality
1
y = - 4x ← in standard form
with k = - 4
2
= 2 ( multiply both sides by x )
y = 2x ← in standard form
with k = 2
3
= 3 ( multiply both sides by y )
x = 3y ( divide both sides by 3 )
x = y ← in standard form
with k =
Y = mx +b whre m is the slope and b is the y-intercept.
We have the slope 3/4 so put that instead of m
y = 3/4x + b
Now to find the y-intercept (b), plug the ordered pair in and solve for b.
-4 = 3/4 * 5 + b
-4 = 15/4 + b
-31/4 + b
So y = 3/4x - 31/4
Answer:
f(3)=2
Step-by-step explanation:
To find f(3), we simply need to find the ordered pair at x=3.
From the graph, we can see that the ordered pair at x=3 is (3,2).
Thus, f(3)=2.
And we're done!
In this situation, there are 2 separate terms (parts of the story). The first part is the information about the coupon that applies to the daily rate of $40. You will represent this as 0.75 (for the 75% that you will be paying) x 40. (The other part of this story is that you are paying $0.15 per mile which is represented as 0.15m. You need to put these together to get 0.75(40) + 0.15m. The 0.25 times 40 can be simplified to say 30, so write it as $30 + $0.15m.
