Nancy and Elsa like to ride bikes. The equation m=12h represents the approximate number of mies m Nancy bikes in h hours . The equation m = 9h represents the approximate number of miles Elsa bikes in h hours . How much longer will it take Elsa to bike 72 miles than Nancy?

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing

step-by-step explanation:

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
