hello I need help I really want to pass this lesson so if you could please help me out! here is the image.

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

Using graph paper, determine the line described by the given point and slope. click to show the correct graph below.(0, 0) and 2/3

Which statements about the system are true? check all that apply. y =1/3 x – 4 3y – x = –7 the system has one solution. the system consists of parallel lines. both lines have the same slope. both lines have the same y–intercept. the equations represent the same line. the lines intersect.
