Answer:
its the first option
Step-by-step explanation:
k should be 1, Check by calculating the x values for f(x) and confronting them with g(x)
To solve, you need to plug in the values they give you into the equation.
5t + 2m
Plug in the numbers they give you
5(2) + 2(7)
Solve.
10 + 14
Simplify.
24
There is 3600 seconds per hour.
Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.
4.9 * 3600 = 17,640 miles per hour
17,640 x 1.6 = 28,224 kilometers per hour
