Answer:
![x \geq -\frac{7}{2}](https://tex.z-dn.net/?f=x%20%5Cgeq%20-%5Cfrac%7B7%7D%7B2%7D)
Step-by-step explanation:
we have
![y=4\sqrt{2x+7}](https://tex.z-dn.net/?f=y%3D4%5Csqrt%7B2x%2B7%7D)
we know that
The radicand must be greater than or equal to zero
so
![2x+7 \geq 0](https://tex.z-dn.net/?f=2x%2B7%20%5Cgeq%200)
Solve for x
Subtract 7 both sides
![2x+7-7 \geq 0-7](https://tex.z-dn.net/?f=2x%2B7-7%20%5Cgeq%200-7)
![2x \geq -7](https://tex.z-dn.net/?f=2x%20%5Cgeq%20-7)
Divide by 2 both sides
![x \geq -\frac{7}{2}](https://tex.z-dn.net/?f=x%20%5Cgeq%20-%5Cfrac%7B7%7D%7B2%7D)
The domain is the interval --------> [-7/2,∞)
For #1 I think maybe 5 qts
Answer:
99 TVs
Step-by-step explanation:
5 and a half hours is about 330 minutes.
9:30 = x:330
If 30 * 11 = 330, then 9 * 11 will equal x.
Judy should inspect 99 TVs.
