Step-by-step explanation:
Answer: f(g(x))= -2x+43
Step-by-step explanation:
Here, you would start by substituting the equation for g(x) into the x value of f(x) equation.
Since g(x)=1/4x+5, f(g(x)) would be:
f(g(x))= 3-8(1/4x+5)
Then you would simplify.
f(g(x))= 3-8(1/4x+5)
= 3-2x+40
=-2x+43
7/8 miles = 49 / 56 miles so it will take the road crew 49 hours to repave the road.
You would write it out like this: 12/20. But yeah, it can be simplified by dividing 4 for 12 and 20. So it would be: 3/5. So 3/5 is the simplest form.
