{(-5,1), (-3,2), (-1,3), (1,4), (3,5)}
Hope this helps!
Answer:
See below ~
Step-by-step explanation:
<u>Perimeter</u>
- 2(6 + 8)
- 2(14)
- <u>28</u> units
<u>Area</u>
- 2(4 x 2) + 2(8)
- 4(8)
- <u>32</u> square units
Answer:
- D. l = 3 || 4 < c < y || 8l + 7.5c ≥ 70
Step-by-step explanation:
<h3>Work at library</h3>
- Time = 3 hours ⇒ l = 3
- Payment = $8 per hour
- Total payment = 8l
<h3>Work at coffee shop</h3>
- Time = between 4 and 7 hours ⇒ 4 < c < 7
- Payment = $7.5 per hour
- Total payment = 7.5c
Target income = at least $70 daily
<u>So the system as per above parameters:</u>
- l = 3
- 4 < c < y
- 8l + 7.5c ≥ 70
Correct option is D
Manipulate the first equation to
y = 22-7z
Then substitute in the second to find z
8(22-7z) + 7z = 127
176-56z+7z = 127
-49z = -49
z = 1
So y = 22-7(1) = 22-7 = 15
y = 15; z = 1
For example, if the question is to simplify square root x^7, you do 7/2=3......1
so the answer would be x^3 times square root x
