Not always it depends on what kind of problem you get. Sometimes you have get a problem that does not have multiplication so then you'd start with division instead.. Get what I'm saying lol? Maybe that helps.
Answer:
3
Step-by-step explanation:
The points they have in bold is probably a hint to the problem.
The points they have in bold are (1,2) on curve g which means g(1)=2
and (3,2) on curve f which means f(3)=2.
g(x)=f(kx)
We know g(1)=2 so if we replace the x's with 1, we get:
g(1)=f(k*1)
g(1)=f(k)
2=f(k).
Now we just need to solve f(k)=2 for k.
We know the point (3,2) is on f so f(3)=2.
If you compare:
f(k)=2
and
f(3)=2
then you should see that k=3.
The graph would have the equation y=6x, with x being money, y being hours,
since she makes $6 an hour($30/5hours = $6/1hours).
