Answer:
x > 0.5
Step-by-step explanation:
Given
- 0.2x + 1.2 < 1.1 ( subtract 1.2 from both sides )
- 0.2x < - 0.1
Divide both sides by - 0.2, reversing the symbol as a result of dividing by a negative quantity.
x > 0.5
D=dollars earned
T=time spent painting the fence.
(1,5) (2,10) (3,15)
D=5T
45 minutes.
3 x
--- ----
4 60
you multiply 60 and 3.
you get 180, then you divide by 4 and get 45 minutes.
We first need to pick the correct piece to use. In this case, we will use f(x) = -x-5 because -5<=-4.
Then, we use direct substitution:
f(-4) = -(-4) - 5
f(-4) = -1
