If k(x) = 2x-3x then k(9) is. a.315 b.307 c.159 or d.153 show work plzz

none of the solutions

Step-by-step explanation:

if k(x) = 2x-3x

We can substitute x=9 to find k(9)

k(9) = 2(9) -3(9)

      = 18 -27

      = -9

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
