1 answer:
Answer: 3996 meters
Step-by-step explanation:
Given: Maya is camping at the top of mount armstrong at an elevation of 7832 meters.
Consider the pont of sea level be 0.
Then the height of the point where Mary is = +7832 meters (by using integers)
Juan is scuba diving 160 meters below sea level.
⇒The height of the point where Juan is =-160 meters
The distance between them =
The mid point of the distance=
Hence, Maya & Juan meet will meet at an elevation of 3996 meters .

Answer:
(a) y = -4x + 4 (b) y = 2x + 3
<u>solving steps:</u>
note: m refers to slope and y₁ to y point and x₁ to x point
a)
coordinates: (2,-4)
slope: -4
equation:
- y - y₁ = m(x - x₁)
- y - -4 = -4(x-2)
- y = -4x + 8 - 4
- y = - 4x + 4
b)
coordinates: (1,5), (-1,1)
slope:
- 2
equation:
- y - y₁ = m(x - x₁)
- y - 5 = 2(x - 1)
- y - 5 = 2x - 2
- y = 2x - 2 + 5
- y = 2x + 3
