Answer:

option C.

Step-by-step explanation:

option C is the correct answer.

Direct variation: y = kx .........where k is constant.

10 = k * -5

k = -2

Then check if all are linear and matches.

y = -2 * -4

y = 8 ...matches.

then

y = -2 * -3

y = 6 ........matches

then

y = -2 * -2

y = 4 ........matches

then

y = -2*-1

y = 2 ......matches as well. so direct variation.

Solve for x in the diagram below
MrRissso [65]

Answer:

x=20 degrees

Step-by-step explanation:

because this is a supplementary angle, you add everything and set it equal to 180 degrees. so it would be x + 100 + 3x = 180. combine like terms to get 100 + 4x = 180. subtract 100 from both sides to get 4x = 80. divide by 4 on both sides to isolate the x and your final answer is 20. hope this helped! good luck in school xoxo

Answer: b
