Answer:
3.5
Step-by-step explanation:
2 1/3 is equal to 7/3 and 2 goes into 7, 3.5 times.
Average rate of change is the same as finding slope between a line on a non- linear function.
Using the ordered pairs
(5,10) and (8,1)
(10-1)/(5-8) = 9/-2 = -9/2
Legs with "B" in their title can not be opposite to the angle B, as they are touching it. So...
The opposite leg to the angle B is the leg AC.
The middle point of BC is (0,2), the midpoint of CD is (1,0)
to prove two lines are parallel, prove their slopes are the same.
slope of BD: m=rise/run=4/-2=-2 (the run is negative because to get to B from D on the grid, you have to move from right to left, then upward. If the horizontal move is from left to right, the run is positive)
slope of EG: m=rise/run=2/-1=-2
EG and BD have the same slope, so they are parallel.
