To find the average speed of the jet, we divide 4000 by 5. When we do so, we get 800. Therefore, the average speed of the jet was 800 kilometers per hour. Hope this helped!
Answer:
Step-by-step explanation:
<u>Equation for the Highland population</u>
<u>Equation for the Lowville population</u>
<u>Populations are equal after</u>
- 12200 + 300x = 21000 - 250x
- 300x + 250x = 21000 - 12200
- 550x = 8800
- x = 8800/550
- x = 16 years
The answer should be y = 5x^2+4x-1
104.349540079
7.61 x 104.349540079 = 794.1
