It takes Brian 12 hours longer to build a model car than it takes John. If they work together, they can build the model car in 8 hours. Using complete sentences, explain each step in figuring out how to determine the time it would take Brian to build the car on his own.

combine all like terms then its just a 2 step equation

where is the graph, sweetheart?

step-by-step explanation:

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.
