Answer:
78°
Step-by-step explanation:
when two lines intersect it creates 4 seperate angles, here it gives us 78°, and we know that the angle across from it is the same, so they equal.
Answer:
The car uses less gas
They use the same amount of gas after
miles
Step-by-step explanation:
Given
The table represents the car mileage
--- The van
First, calculate the car's slope (m)

From the table, we have:

So, we have:



Calculate the equation using:



implies that for every mile traveled, the car uses 1/40 gallon of gas
Also:
--- The van
By comparison to: 

This implies that for every mile traveled, the van uses 1/5 gallon of gas.
By comparison:

This means that the car uses less gas
Solving (b): Distance traveled for them to use the same amount of gas.
We have:
--- The van
--- The car

Answer:
$1,280 every year and $106.66 every month.
Step-by-step explanation:
You would do 4,000 by 4. Which would be 1,000. Then you would divide 560 by 4. After, you add both of your products together and you get 1,280. Obviously there are 12 months in a year, so you would divide your sum by 12. Then you would get 106.66. Basically, that is how you would get the answer.
I hope this helps!

Find the slope (m) by using Y2-Y1/X2-X1
Y2 = -1
Y1 = 7
X2 = 4
X1 = 2
(-1 - 7)/((4-2) = -8/2 = -4
Use the point-slope formula to determine the equation. You only need to use one set of points. (2,7) in this case.
(y-Y1) = m(x-X1)
(y - 7) = -4(x - 2)
y-7=-4x + 8
y= -4x + 15
The answer would be 10 because when you divide 7.5 by .75 it goes in 10 times
