Mary has some trading cards. Julie has 3 times as many trading cards as Mary. They have 36 Trading cards in all. Which equation represents their trading card collection?

the equation that is equal to X+3X=36

Step-by-step explanation:

since they have 36 all together, we know thier total is 36. since it says that julie has three times mary, i used x to represent mary. so julie is 3x. now we know the equation x(Marie)+3x(JUlie)=36(total)

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.

answer: check all that apply, where the options?
