Answer:
Step-by-step explanation:
m∠JXM + m∠NXP = 180° - m∠MXN = 90°

-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:
addition of 254 to both side
16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
The equation y=mx+b
Slope= m
y-intercept= b
y= 2x+0 so y=2x
