The answer is -8
because f(x+1) where x= -9
-9+1 = -8
M/8 = 21/6
m = 8 *21 / 6
m = 28
answer
D . 28
two hundred ninety-six ten thousandths
X = large boxes and y = small boxes
x + y = 70.....x = 70 - y
60x + 65y = 4300
60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs
x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs
