Answer: Hello! Hope this helps.
Step-by-step explanation: 6 - 7x/2
So its the first answer.
Setup a right triangle with the boat on top. Striaght down is 40 feet. The rope makes the hypotenuse at 140 feet. The floor of the ocean makes the third side.
40^2 + x^2 = 140^2
When you solve for "x" you get 134.2 feet.
Hope that helps.
Answer:
y=-x-2
Step-by-step explanation:
To find the slope of the line, you can use the slope formula. I did this with (-3,1) and (2,-4) to get: (1+4)/(-3-2). This ends up as -5/5, which simplifies to -1.
next I plugged in the slope and one point into the line equation: y=mx+b. I plugged in (-4)=(-1)(2)+b. This equated to b=-2.

The equation -4=(-1)(2)-2 is true
The equation 1=(-1)(-3)-2 is true
