How do I solve without s calculator?
baherus [9]
You could solve it ( without a graph) in 2 easy ways :

1 use the equation that you have written in pencil and solve for y

y=3=-x+4
y=-x +1

Or you could use the point slop form after you find the y intercept y=mx+b


-3=4(-1)+b
b= 1

So the answer would be y= -x +1


Hope this help of it does feel free to give the brainliest

A boat drops an anchor 75 feet to the bottom of a lake. A sunken treasure chest lies at the bottom of the lake, 40 feet away fro
Reil [10]
Given
Height (length) of the anchor dropped from the boat = 75 feet
Distance of the treasure from the anchor = 40 feet

Solution
The dropped at the bottom makes an angle of 90 degree . Therefore making an right triangle with the chest and boat

By Pythagoras theorem
AC^2 = AB^2 + BC^2

(AC = distance of the treasure from the boat
AB = height of the anchor dropped from the boat
BC = the distance of treasure from the anchor)

AC^2 = 75^2 + 40^2
AC^2 = 5325 +1600
AC^2 = 6925
AC = 25 * (under root 11)

Therefore they have cover a distance of 25 * (under root 11)
