Answer:
80 mph
Step-by-step explanation:
step 1
Find the distance traveled by Miriam the first two hours
Remember that the distance is equal to the speed multiplied by the time
we have
so
9:00 AM +2 h=11:00 AM
At 11:00 am Miriam has travel 140 miles
step 2
Find out the speed
Remember that the speed is equal to divide the distance by the time
The time is equal to
6:00 PM-11:00 AM=7 h
the distance is equal to
700-140=560 miles
therefore
<span>2x^2 + 3x – 54 = </span>(2x - 9) (x + 6), so A and F
Find f(18)
g(f(18))=
g(5/6(18)+5)=
g(15+5)=
g(20)=
5(20)+6=
100+6=
106
selling price is $106
