Answer:
D
Step-by-step explanation:
To solve this you just set the two equations equal to each other and solve for x
-4x+9= -x+6
-3x=-3
x=1
Answer:
2.4 hours
Step-by-step explanation:
David's time = 6 hours
Anthony's time = 4 hours
the combined time is given by the following formula
1/ (david's time) + 1/(anthony's time) = 1/total time
1/6 + 1/4 = 1/Total
4/24 + 6/24 = 1/Total
10/24 = 1/ total (taking reciprocal of both sides)
24/10 = total
total time = 24/10 = 2.4 hours
The slope of the line is 2 if that is what you're looking for
