F(x) = 20x+300
you sub in the x values (120 hours and 100 hours) for each equation
the only one they both work for is the last one
f(x) = 20x + 300
f(100) = (20 * 100) + 300 = 2000 + 300 = 2300
f(120) = (20 * 120) + 300 = 2400 + 300 = 2700
A.) y = x - 4
b.) y = 8x
c.) y = 12x - 4
d.) y = x - 4
I am like 90% positive this is right but don’t count on it. I tried.

Answer:
#6 is 17 days
Step-by-step explanation:
This is how I answered it
1) 2750 = 550 + 125x
2) subtract 550 from each side
2750-550=2200
so the left over equation is:
2200 = 125x
3) divide each side by 125 to get x by itself
2200÷125= 17.6
4) you are left with: x = 17 days
Answer:
Part A: the dependant variable is how many hours he works mowing lawns.
the independent variable is that she earns $7 per hour.
Part B:(1,7) 1 hour working for $7
(2,14) 2 hours working for $14
(3,21) 3 hours working for $21
Part C: Y=7h (h represents the number of hours she works)
Step-by-step explanation:
I'm not 100% sure about part A I have not done this in a while but here you go
