The graph below shows the relationship between the amount of water left in a tank after Kelsey made a whole for the water to drain for a couple of hours. Write a function that shows the relationship of the water, W, left in terms of, t, time. Help me please I gotta turn this in before the end of the day Please help me​

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

d

step-by-step explanation:

i used the pitagoras theoreme

definitely a. the others have almost all data points on one side of the line.

step-by-step explanation:

its an acute right triangle
