Answer:
the answer would be 36.
Step-by-step explanation:
and here go you would get it
R(-5) = -3*(-5) - 4
R(-5) = 15 - 4
R(-5) = 11
Q(X)=3X+3
Q(11) = 3*11 + 3
Q(11) = 33 + 3
Q(11) = 36
So, (Q(R(-2) = 36
hope it is correct..
Step-by-step explanation:
Since ∠E is right angle, its opposite side is DF and the legs are DE and EF.

Answer:
2.8 hours
Step-by-step explanation:
Distance = rate * time
If the west-bound train travels at a rate of 80 mph for t hours, then the distance it travels is 80t.
If the east-bound train travels at a rate of 90 mph for t hours, then the distance it travels is 90t.
The distance between the trains after t hours is 476; therefore, the distance of the west-bound train plus the distance of the east-bound train equals the total distance between them, 476:
80t + 90t = 476 and
170t = 476 so
t = 2.8 hours
