Answer:
2x 4 +3x 3 +x 2 −5x−18
Step-by-step explanation:
Based on the fact that the scuba diver was below sea level, the expression that shows their distance after 30 minutes is -120.9 - 42.5 and the elevation is -163.4 feet.
<h3>What is the diver's elevation?</h3>
Because the diver is below sea level, their elevation will be expressed in negatives.
This means that the elevation is -120.9 feet.
If the diver's elevation decreases by 42.5 feet, the equation for the new elevation is therefore:
= -120.9 - 42.5
When solved, this is:
= -163.4 feet

Answer:
y = -2x + 4
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Slope of a line passing through two points 
and 
is given by,
m = 
Slope of a line passing through (0, 4) and (2, 0) will be,
m = 
= -2
Y-intercept of the line 'b' = 4
Therefore, equation of the line will be,
y = -2x + 4
