The function with a rate of change of 3/2 whose graph passes through the point (4,10.5)

The function is f(x) =   x +  

Step-by-step explanation:

The point-slope form of a linear function is , where

∵ The function has a rate of change  

- The rate of change is the slope of the graph

∴ m =  

∵ The graph is passes through point (4 , 10.5)

∴ = 4 and = 10.5

Substitute m and the coordinates of the point in the form of the equation

∵

∴ y - 10.5 = (x - 4)

Simplify the right hand side

∴ y - 10.5 =   (x) -   (4)

∴ y - 10.5 =   x - 6

Add 10.5 to both sides

∴ y =   x + 4.5

∵ 4.5 =

∴ y =   x +

∵ y = f(x)

∴ f(x) =   x +

The function is f(x) =   x +  

answer: b.36 feet

step-by-step explanation:

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
