CAN SOMEONE PLEASE HELP YOU WILL BE MARKED AS THE BRAINLIEST AND AWARDED LOTS OF POINTS AND 5 STARS WITH A THANKS

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.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
