Park has two sprinklers that are used to fill fountain one sprinkler can fill the fountain and three hours whereas the second sprinkler can fill the fountain in six hours how long will it take to fill the fountain with both sprinklers

answer: what equations are there

step-by-step explanation:

y > 1/3x

y < = -x + 4

hope this : )

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
