Answer:
The required number of ropes is 9.
Step-by-step explanation:
The length of rope is 65 ft.
The distance to the base of cliff was 585 ft.
Let the number of ropes or same lengths did it take climber to reach descent be x.
Divide both sides of 65.
Therefore the required number of ropes is 9.
Step-by-step explanation:
An equation to keep in mind is y=mx+b
m=
Any two coordinates would be good for this formula
For example you could use (2, -4) and (3, -7)
(3, -7) would be your second coordinate
(2, -4) would be your first coordinate
-7 =
3=
-4=
2=
Put the values into the formula and solve
=
=
= -3
m= -3
Now you have y=-3x +b
There are 2 ways to find b, but I will show the one that is the easiest to explain for me
1) substitute the x and y coordinates from one of the coordinates into the 'new' formula
I will be using the coordinate (2,-4)
y = -3x + b
-4 = - 3(2) +b
-4 = -6 +b
-4 +6 = -6 +6+b
2 = b
Your updated equation is y=-3x+2
The answer is the second option
I hope this helps!!!
