One company wants $10 per 3.5 hours, so they want 10 / 3.5 ≈ 2,86 dollars per hour (after rounding to the closest hundreths).
Second company wants $1.25 per half an hour, so they want 2 * 1,25 = 2,50 dollars per hour.
The unit rate is 2,86:2,50

Answer:
<u>f</u><u>(</u><u>-</u><u>2</u><u>)</u><u> </u><u>+</u><u> </u><u>9</u><u> </u><u>is</u><u> </u><u>1</u><u>9</u>
Step-by-step explanation:
![f(x) = - 3x - 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20-%203x%20-%202)
when x is -9:
![f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10](https://tex.z-dn.net/?f=f%28%20-%202%29%20%3D%20%20-%203%28%20-%202%29%20-%202%20%5C%5C%20f%28%20-%202%29%20%3D%2010)
sum up with 9, f(-2)+9:
![f( - 2) + 9 = 10 + 9 \\ = 19](https://tex.z-dn.net/?f=f%28%20-%202%29%20%2B%209%20%3D%2010%20%2B%209%20%5C%5C%20%20%3D%2019)
