There are 15 students in my sisters class and she has four pieces of paper she needs to give each student a fourth of a paper does she have enough pieces of paper

No there will be one extra.

Step-by-step explanation:

15 divided by 4 is 12 remainder 1

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.

maya’s expression will generate the wrong sum because she violated the commutative property.
