Answer:
The answer is below
Step-by-step explanation:
a) Let x represent the time taken to drive to see the relatives and let d be the distance travelled to go, hence:
60 mi/h = d/x
d = 60x
When returning, they still travelled a distance d, since the return trip takes 1 h longer than the trip there, therefore:
40 mi/h = d/(x+1)
d = 40(x + 1) = 40x + 40
Equating both equations:
60x = 40x + 40
60x - 40x = 40
20x = 40
x = 40/20
x = 2 h
The time taken to drive there = x = 2 hours
b) The time taken for return trip = x + 1 = 2 + 1 = 3 hours
c) The distance d = 60x = 60(2) = 120 miles
The total distance to and fro = 2d = 2(120) = 240 miles
The total time to and fro = 2 h + 3 h = 5 h
Average speed = total distance / total time = 240 miles / 5 h = 48 mi/h

6 to the 16 power
The function g(x) created after transformation of f(x) is gotten as; g(x) = 2x³ + 4
<h3>How to Interpret transformation graphs?</h3>
From the graph attached, we see that the coordinates of function g(x) are;
At x = -1, g(x) = 2
At x = 0, g(x) = 4
At x = 1, g(x) = 6
Looking at the options, the only one that has this correct input and output values is option C.
