Alex is making 12 pennants for the school fair. the pattern he is using to make the pennants is shown in the figure. the fabric costs $1.25 per square foot. how much will it cost alex to make 12 pennants?

It will cost Alex $52.5 to make 12 pennants

Step-by-step explanation:

The area of the pennant is the area of the rectangular portion plus the area of the triangular portion.

The area of 12 pennants

If the fabric for the pennants costs $1.25 per square foot, then;

42 square feet will cost dollars.

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.
