4.) A helicopteris traveling at a speed of 48 miles per hour (mph). Its speed will increase at a constant rate of 23 mph every 2 second. How fast will the helicopter travel after'x' seconds ?

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

If f(x) = x+8 and g(x) = 4x- 3, find (f+g)(x)

M the table below represents a linear function f(x) and the equation represents a function g(x): x f(x)−1 −50 −11 3g(x)g(x) = 2x − 7part a: write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x). (6 points)part b: which function has a greater y-intercept? justify your answer. (4 points)
