B is the answer I think I spend to much
Your new line has to have the same slope as the green line for them to be parallel, so start off with y=-3/4x+b.
Plug in (2,4) into the new line so 2 for x and 4 for y
It should look like 4=-3/4(2)+b
-3/4x2 is -1.5
Then add 1.5 to both sides and you should get 5.5=b
Your new line is y=-3/4x+5.5 and (0,5.5) is a point on the line
Answer:
The cost of renting will be the same for 200 miles.
Step-by-step explanation:
Let n the number of miles and C be the cost. We can represent the cost equations for each companies:
A: C = 12 + 0.09n
B: C = 8 + 0.11n
They want to know when the cost will be the same, so we can set the above 2 equations equal to each other and solve for n:
12 + 0.09n = 8 + 0.11n
0.02n = 4
n = 200
Answer: 200 literes will be used in an hour
Step-by-step explanation:
1. 150 divided by 45 mins = 3.3 recurring
2. 3.3 recurring times 60 ( 60 mins in an hour) = 200
