Answer:
16
Step-by-step explanation:
distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Answer:
The midpoint is (-6,-4)
Step-by-step explanation:
The formula for the midpoint is
M = (x1+x2)/2, (y1+y2)/2
Substituting what we know
= (-8+-4)/2, (-1+-7)/2
= -12/2, -8/2
= -6, -4
When working with functions (of all types), the average rate of change is expressed using function notation:

For the interval from x=7 to x=8,
1. find f(7) and f(8):
2. use given formula:

Answer: the average rate of change for the interval from x=7 to x=8 is 4374.
Answer:
x ≤ -12
Step-by-step explanation:
Answer:
17%
Step-by-step explanation:
to find the percentage of something, you have to fill out the following formula:
x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:
125x = 2125
then you have to divide, to single out x:
the answer is 17
so it is 17%
