Step-by-step explanation:
h(x) = 3. g(x) + 5
x= -1 h(x) = 3×8 + 5= 29
x= 0h(x) = 3×5 + 5= 20
x= 2 h(x) = 3×1 + 5= 8
x= 5 h(x) = 3×-5 + 5= -10

im sorry if im wrong but im just trying to help out and please correct me if ime wrong
The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
Answer:
7:24 pm
Time taken will be longer
Step-by-step explanation:
Given that:
Distance between Manchester and London = 195 miles
Departure time = 3.30 pm
Average speed of Coach = 50 mph
Arrival time in London :
Time taken = distance / speed
Time taken = 195 / 50 = 3.9 hours (3 hours (0.9 * 60) = 3 hours 54 minutes
= 3:30 pm + 3 hours 54 minutes = 7:24 pm
If the speed is Lower then the Timetaken will be longer and subsequently coach will arrive after 7:24 pm
