Answer:
(3,2) Choice C
Step-by-step explanation:
x-2y = -1
2x+3y =12
multiply the first equation by -2
-2x +4y = 2
add the 2 equations together
2x+3y =12
-2x +4y = 2
-----------------
7y =14
divide by 7
y =2
x-2y = -1
x -2(2) = -1
x-4 = -1
add 4 to each side
x = 3

6 Pallets per hour.
If there are 9 that need to be done in 1.5 hours, we have 9 in 90 minutes. If we divide that by 9, we get 1 every 10 minutes. If we multiply that to get an hour, we get 6 done in 60 minutes.
(F*g) means f ( g(x) ) . Knowing this we can say
F(g(x)) = 3(5-x) ^2
= 3 (5-x)(5-x)

The median is 10.5 because its the middle line in the box and all you have to do is look at it and you can see it
