Answer:
x ≥4
Step-by-step explanation:
-4(8-3x) ≥6x-8
Distribute
-32+12x ≥6x-8
Subtract 6x from each side
-32+12x-6x ≥6x-6x-8
-32+6x ≥-8
Add 32 from each side
-32+32 +6x ≥-8+32
6x ≥ 24
Divide each side by 6
6x/6 ≥24/6
x ≥4
Using the exponential function, it is found that the oxygen level at 10 miles is of 59.87 ppm.
<h3>What is the exponential function for the oxygen levels?</h3>
The oxygen levels in ppm for an altitude of x miles at the Mount Everest is given by the following exponential function:
![O(x) = 100(0.95)^x](https://tex.z-dn.net/?f=O%28x%29%20%3D%20100%280.95%29%5Ex)
In this problem, the altitude is of x = 10 miles, hence the oxygen level in ppm is of:
![O(10) = 100(0.95)^{10} = 59.87](https://tex.z-dn.net/?f=O%2810%29%20%3D%20100%280.95%29%5E%7B10%7D%20%3D%2059.87)

Add like terms and that should be the simplified versions for the answer:
15r.
I think because she has more harder stuff
