First we must divide 9 by 3.

9/3 = 3

Then multiply it by 8

3*8 = 24. Hope this helps!

If eight students lose their metro cards every three weeks then in six weeks sixteen will have lost theirs, and in nine weeks twenty-four will have lost theirs. (I think I did that right)
Hope this helps!

ser-zykov [4K]

Answer:

Below in bold.

Step-by-step explanation:

300 degrees - reference angle is |360 - 300 |= 60 degrees

225 = 225 - 180 = 45 degrees

480 = 480 - 360 = 120 so it is 180 - 120 = 60 degrees.

-210 = |-210 + 180| = 30 degrees.

Evaluate the function <br> f(8) + g(-1) for the functions f(x) = -2x + 9 and g(x) = x²-2

EastWind [94]

Answer:

- 8

Step-by-step explanation:

To evaluate f(8) substitute x = 8 into f(x)

f(8) = - 2(8) + 9 = - 16 + 9 = - 7

Similarly for g(- 1)

g(- 1) = (- 1)² - 2 = 1 - 2 = - 1

Then

f(8) + g(- 1) = - 7 + (- 1) = - 7 - 1 = - 8
