Answer: See explanation
Step-by-step explanation:
7.) (0, 2)
Slope of (0, 2) and (-10, -16) = 2 - (-16) ÷ 0 (-10) = 18/10 = 9/5
8.) a. Slope of (17, -12) and (17, 8)
8 - (-12) ÷ 17 - 17 = 20 ÷ 0 = undefined
b. Slope of (6, -2) and (-3, 1)
1 - (-2) ÷ -3 - 6 = 3/-9 = -1/3
9.) (-3, 33) and (4, -9)
-9 - 33 ÷ 4 - (-3) = -42/ 7 = -6
10.) Hourly: c = 75h + 15
c - charge
h - hours
1 hour
c = 75 (1) + 15
c = 75 + 15 = 90
The hourly charge for services is $90.
11.) C. A newborn weighs 8 pounds and gains 1.5 pounds each month for the next 3 months.
12. 2(x + 2)(x - 3)
It would be the third response
13. The GCF is x
I think it would relate to 28 hrs. in 8 days seeing as how 28:8 could be simplified to 14:4
Answer:
$71
Step-by-step explanation:
9 + 70 - 8 = 71
