The empty gas tank of a motor boat is to be filled. The tank is shaped like a rectangular prism with length 20 cm, width 15 cm, and height 15 cm. Suppose gas is pumped into the tank at a rate of 450 cm per minute. How many minutes does it
take to fill the empty tank?

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

i belive those are the ones that are under 90 degreese.

it would open into a square depending on the type of envelope i’m not sure about the second part
