Note that 2x-y=8 can be solved for y: y=2x-8. This is identical to the first equation. The graph of one is exactly the same as the graph of the other. Thus, the two equations are dependent.
Answer:
he just shrugged and *sigh*
Step-by-step explanation:
63+12x<15
12x<-48 (subtract 63 from both sides)
x<-4 (divide out the 12)
Answer:
y = 38 + 72t - 16t^2
Step-by-step explanation:
So, solve for t when y=48.
The max height is of course, when t = 64/32 = 2.
