hi
-16t²+250 = 75
-16t² = 75 -250
-16t² = -175
t² = -175 /-16
t² = 175/16
Here there si two solutions : t =
and t = - 
However, as time cannot rewind, we will keep only positive solution
So t = 
in seconds it will be : 3.3 seconds
Answer:12
Step-by-step explanation:
Answer:
-2/3
Step-by-step explanation:
because this is in slope intercept form, m is the slope, so in this case -2/3 is the slope
parallel lines always have the same slope and different y-intercepts
a parallel line could be y=-2/3 +15
Answer:
6/7
Step-by-step explanation:
45x+34=24x+16
collect like terms, we now have;
45x-24x=16-34
21x=-18
X=18/21
X=6/7
I have drawn the graphs.you can get from them,maybe turn left 2
