labwork [276]

Answer:

y = - 400 + 700x

Step-by-step explanation:

Nour's altitude increased at a constant rate from the Dead Sea up to Amman.

Initially, her altitude was 400 meters below from the sea level and then she arrived at an altitude was 1000 meters above sea level arrived to Amman, 2 hours later.  

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

200 + 20x ≥ 500 I don't get these
Vikentia [17]

Answer:

x ≥ 15

Step-by-step explanation:

200 + 20x ≥ 500

To solve this inequality, you must first subtract 200 from 500.

500 - 200 = 300.

Lastly, divide 300 by 20.

20x = 300

300 ÷ 20 = 15

Therefore, the value of x is 15.
