Jacob hired handyman to fix his roof the handyman charge to send the total of $1650 which included a $848 charde for the parts needed.he asked for a breakdown of the bill and noticed that the work done to his roof after t hours can be modeled by the equation 1650=848+40.1tfor how many hours did the handyman work on the roof?

In order to find the number of hours that the handyman took to work on the roof, you need to isolate "t".

Here we go:

1650 = 848 + 40.1t

subtract 848 from each side of the equation

802 = 40.1t

divide both side of the equation by 40.1

20 = t

So the handyman worked for 20 hours on the roof!

There you go! I really hope this helped, if there's anything just let me know! :)

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
