Person A can finish a job in m days, and person B can finish it in n days. What's the fraction they finish if they work together for one day

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

square root

step-by-step explanation:

the anwser is d) 75°

the answer is  

d.
