Answer:

give me brainliest now plsssss

Step-by-step explanation:

(8x-22)=5x+29

We get rid of parentheses

8x-5x-22-29=0

We add all the numbers together, and all the variables

3x-51=0

We move all terms containing x to the left, all other terms to the right

3x=51

x=51/3

x=17

So, she moves (400 + 1000) = 1400 meters in 2 hours.

Therefore, her rate of change of altitude is \frac{1400}{2} = 700 meters per hour.

Therefore, if y represents Nour's altitude in meters relative to the sea level after x hours then the relationship between the altitude and number of hours is given by
