Answer:

y = 4x-3

Step-by-step explanation:

First we need to determine the slope

Using two points on the line (0,-3) (1,1)

Using the slope formula

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

= (1- -3)/(1-0)

(1+3)/ (1-0)

We know the y intercept, -3

y = mx+b where m is the slope and b is the y intercept

y = 4x-3

A pipe can fill a tank in 120 minutes while the drain can drain it in 150 minutes. If the drain is left open and the fill pipe i

Answer:

600 minutes or 10 hours

Step-by-step explanation:

We can solve this problem by looking at the net increase per minute. To find this, we can set rates for each value.

The pipe will be able to fill 1/120 of the tank in a minute, and the drain will drain 1/150 in a minute. So subtract the two:

1/120 - 1/150 = 1/600 of the tank per minute

Therefore you need 600 minutes to fill the tank, or 10 hours.
