Members of the service club at Rebecca's school must spend a minimum of 20 hours doing volunteer work each semester. The number of hours spent volunteering at school activities can be no more than twice the number of hours spent volunteering outside of school. When x represents the number of hours spent volunteering in school and y represents the number of hours spent volunteering outside of school, this situation can be modeled by a system of inequalities.

Which ordered pairs represent solutions to the system?

(12,5)
(7,11)
(15,6)
(8,16)
(0,22)
(10,10)

4x and 6y

im not sure though

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
