Answer:
Step-by-step explanation:
You can't ever let this go negative. At least not at the grade you are in.
It can be 0.
So the domain must start at x = 7
sqrt(5*7 - 35) = sqrt(0) = 0
x can have any value (including 7) between 7 and infinity. If you choose a number less than 7 (like 6) the square root will go negative and that's not to be done.
So the interval is
7 ≤ x < ∞
A = pq/2
p = diagonal 1
q = diagonal 2
First you woyld find how many hours total he worked.
![5 \times 8 = 40](https://tex.z-dn.net/?f=5%20%5Ctimes%208%20%3D%2040)
Then take the number of hours and multiply by the pay earned per hour.
![40 \times 9 = 360](https://tex.z-dn.net/?f=40%20%5Ctimes%209%20%3D%20360)
They would make $360 per week.
