Murphy is doing a duathlon which consists of a 10-mile running portion and a 40-mile biking portion. Enter an equation that shows the pace, in minutes per mile, that Murphy needs to run (r), as well as the pace, in minutes per mile, that he needs to bike (b) in order to complete the duathlon in 220 minutes.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

the median is   36 orr sum like dat

step-by-step explanation:

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

b segment jm is correct i think
