Janis is the set designer for a play. She has 40 feet of dividers to use to create a section in the workshop for storing props. She plans to create the space in the corner of the workshop and use the dividers to create the extra two walls. The area of the sectioned off space, A, is modeled by this equation, where x is the width of the prop section. - 12 + 400 Which equation reveals the dimensions that will create the maximum area of the prop section?

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.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
