<span>The expression 2x + 50 represents the elevation above sea level of the climber. It can be written as a function as follows:
f(x) = 2x + 50 where f(x) is the height and x is time.
We can obtain the initial height when we set time 0 in which the climber has not started climbing yet. Therefore, the initial height of the climber would be 50 meters above sea level.</span>

Answer:
53 divided by 12 is 4.4167
Step-by-step explanation:
Answer:
5x + 4y = 20
Step-by-step explanation:
(x1,y1) and (x2, y2)
(0, 5) and (4 ,0).
From equation of a line
y2 - y1/x2 - x1 = y - y1/ x - x1
Where x1 = 0, y1 =5 , x2 = 4 , y2 = 0
Imputing values,
0- 5/4-0 = y - 5 / x - 0
-5/4 = y -5/x
Multiply both sides by 4x I. E lcm of 4 and x
4x × -5/4 = y-5/x × 4x
-5x = 4(y - 5)
-5x = 4y - 20
Add 5x to both sides
-5x + 5x = 5x + 4y - 20
5x + 4y - 20 = 0
Add 20 to both sides
5x + 4y - 20 +20 = 0+20
5x + 4y = 20
