Would it help if you wrote it as
?
Then you can cross multiply if you know how to do that.
1*x = (-11)(-3)
x = 33 but what happened to the 2 minus signs?
Remember that a ( - ) times a ( - ) = a plus. The two minus signs become a plus.
is |-13+2| equal to |10+1|? If so explain why, and if not state what each absolute value equals. PLZ I NEED HELP!

Step-by-step explanation:
<u>Part A</u>
The average rate of change of a function over the interval is equal to
, hence:
Therefore, the average rate of change of over the interval
is
.
<u>Part B</u>
Do the same thing as in Part A:
Therefore, the average rate of change of over the interval
is
.
<u>Part C</u>
To interpret our answer from Part B in terms of the real world it represents, we say that between 0.25 seconds and 1 second, the ball falls at a rate of 4 feet per second (since our average rate of change is negative).
Answer:
FG = 18
Step-by-step explanation:
FD is an angle bisector and divides the opposite side into segments that are proportional to the other 2 sides, that is
=
( cross- multiply )
54x = 24(x + 10)
54x = 24x + 240 ( subtract 24x from both sides )
30x = 240 ( divide both sides by 30 )
x = 8
Then
FG = x + 10 = 8 + 10 = 18
