Answer:
The change in elevation is -134 ft
Step-by-step explanation:
Given;
initial depth of the submarine, d₁ = 235 ft
final depth of the submarine, d₂ = 101 ft
The change in the elevation of the submarine is given by;
Δd = d₂ - d₁
Δd = 101 ft - 235 ft
Δd = -134 ft
The change in elevation is negative because the submarine is moving closer to the surface.
Therefore, the change in elevation is -134 ft
Answer:
y = -3x - 5
Step-by-step explanation:
3x - y = 5
+3x +3x
-1y = 3x + 5
---- ----- -----
-1 -1 -1
y = -3x - 5
2x+6x+8=32
8x+8=32
-8 =-8
8x=24
8/8=x 24/8 =4
x=4
