Answer:

Step-by-step explanation:

If the equation is in the form ...

y = ( )

then replace y with f(x).

If it is not in that form, solve for y so it is in that form.

The only equation that needs to have a solution is ...

y +4 = x

Subtracting 4 from both sides gives ...

y = x -4 ⇒ f(x) = x -4

The match is ...

f(x) = -3x -4
f(x) = x -4
f(x) = x +4

On a 15 hour trip, Rob drove 35% of the time and Mark drove the remainder of the time. How many hours did Mark drive? Explain 9.

Zigmanuir [339]

Answer:

9.75 hours

Step-by-step explanation:

If Rob drove 35% of the time and Mark drove the remainder of the time, the total is 100 %

100-35 = 65

so Mark drove 65% of the time

The total time driven was 15 hours, so we multiply the total time driven by the percentage of time that Mark drove to find the number of hours that Mark drove.

15 * 65%

15*.65

9.75 hours
