Answer: okay
Step-by-step explanation:
3 hours = 12 miles
1 hour = 12 ÷ 3 = 4 miles
Answer: 4 miles
Using linear and composite functions, it is found that the x-intercept of g(h(x)) is
, given by option B.
-------------------------------
The equation of a line is:

In which:
- m is the slope.
- b is the y-intercept.
Function g:
- Two of the points are (-6,16) and (-4,10).
- The slope is given by <u>change in y divided by change in x</u>, thus:

Thus:

Point (-4,10) means that when
, and we use this to find b, so:



Then

Function h:
- Two of the points are (-6,-11) and (-4,-7).
- The slope is:

Thus:

Point (-4,-7) means that when
, and we use this to find b, so:



Then

The composite function is:

The x-intercept it the zero of the function, thus:



Which is option B.
