Step-by-step explanation:
Masukkan nilai tersebut dalam persamaan v = u + at,
42 = -8 + (-5)t
50 = -5t
t = -10

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
the graph in the attached figure
we have
using a graphing tool
the roots are ( x-intercepts) x=-0.5,x=1,x=3
the y-intercept is the point (0,3)
