Answer:
it would be something along the lines of. 5+25d =c
Step-by-step explanation:
98 = 188t - 16t^2
-16t^2 + 188t = 98
-16t^2 + 188t - 98 = 0
8t^2 - 94t + 49 = 0
Use the quadratic formula with a = 8 , b = -94 , c = 49 to get the solutions
t = [(47 - root 1817) / 8]≈ 0.55
and
t = [(47 + root 1817) / 8] ≈ 11.20
Subtract 84 on the other side of the equal sign and bring down c and the answer you get from 111 - 84.
It is y = 3x + 2, which means the y-intercept is 2. :)
