F(x) = a.x . We ha to calculate a.
Back to the table, let's rewrite the coordinates
A(0,0)
B(2,-1)
C(4,-2)
D(7,-3.5)
We know that constant is called slope or coefficient is equal to:
a=y/x
Apart from A, in each of the coordinates y/x =-1/2 & this is the slope of the equation f(x) = (-1/2)x
660 feet
given distance varies directly with time (t) then
d = kt ( k is the constant of variation )
find k using the condition d = 264 when t = 0.5
k =
=
= 528
thus d = 528t
when t = 1.25
d = 528 × 1.25 = 660 feet
The answer would be 18 minutes.
15/9 = 30/x
cross multiply
15x=270
then divide
x=18
