David should buy Car A because it covers more miles in one gallon than Car B
Step-by-step explanation:
Given
Distance traveled by Car A =
Gallons used by Car A =
Distance traveled by Car B =
Gallons used by Car B =
In order to find the distance traveled on one gallon, we will divide the total distance by number of gallons
So,
Distance traveled by Car A in one gallon =
Distance traveled by Car B in one gallon =
We can see that Car A travels more distance in one gallon that is 58.5 miles per gallon
So,
David should buy Car A because it covers more miles in one gallon than Car B

we know that
The measure of the interior angle is the half sum of the arcs comprising it and its opposite
so
m∠CED=
see the attached figure with letters to better understand the problem
° ------> by central angle
° ------> by central angle
Substitute the values in the formula above
m∠CED=
m∠CED=
m∠CED=°
therefore
<u>the answer is</u>
m∠CED=°
C because it crosses the y-axis at -3 and it goes up at a rate of rise 1, right 1
