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
Plug the values into point slope and simplify
y-4= 4(x-(-2))
y-4= 4x+8
y= 4x+12
Final answer: y=4x+12
The correct answer is 1/8.
Answer:
A: yes
B: 40
C: 1x=40
I'm not really sure about C btw.
