Between 2pm and 4pm the average rate of change is zero.
I can't see the answer choices for the second part of the question.
Alright.
For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:
3x+2=23
2y-7=9
Solve using GEMDAS/PEMDAS, and you'll get these answers.
3x+2=23
3x=21
x=7
2y-7=9
2y=2
y=1
For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:
3y+5=14
2x-5=17
Solving them would make:
3y+5=14
3y=9
y=3
2x-5=17
2x=22
x=11
For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:
130=2h
5k=50
solve them and you get
h=65
k=10

Hope that helped. Good luck.
The answer is (-2, -3) since 2*-2–(+)3= -1 and 2*-2-4*-3= 8.
Answer:

Step-by-step explanation:
<u>To figure this question out, you must follow the rule:</u>
Parenthesis
Exponent
Multiply
Divide
Addition
Subtraction
As you can see, the first operation in PEMDAS is Parenthesis.
Meaning the first thing you do is the numbers in parenthesis
