Hope this helped you!
Answer:
x=4, y=3 (4,3)
Step-by-step explanation:
- x=7−y
19+y=22
y=3
-Substitute y=3y=3 into x=7-yx=7−y.
x=4
Answer:
The hiker's elevation after 145 minutes will be 1958 meters.
Step-by-step explanation:
The equation of the trend line of the scatter plot showing a hiker's elevation is y = 8.77x + 686 .......... (1), where x is in minutes (say) and y is in meters (say).
Now, we have to predict the hiker's elevation after 145 minutes.
So, from equation (1) we get, y = 8.77 × 145 + 686 = 1957.65 ≈ 1958 meters. (Answer)
The answer is C. $1,600 because you multiply 200 by the cost of the ticket.
