The scatter plot shows a hiker's elevation above sea level over time. The equation of the trend line shown is y = 8.77x + 686. T
MatroZZZ [7]

Answer:

707 feet above sea level

Step-by-step explanation:

2 hours and 25 minutes is about 2.4167 hours.

Therefore:

y=8.77x+686

y=8.77(2.4167)+686

y=21.1944+686

y=707.1944

So the hiker's elevation will be approximately 707 feet above sea level

Y= -x^2+10x-25 in factored form and what is the x intercept
Strike441 [17]

Step-by-step explanation:

-(x² - 10x + 25) = 0

x² - 10x + 25 = 0

(x - 5)(x - 5) = 0
