Can someone help me with 29? Thank you :)

You have to draw it

Step-by-step explanation:

Draw the graph or the points on a piece of paper.

Getting the reflection is not that difficult, you would have to each point of y axes, and flip it on the y coordinate. The distance of the reflected point, should be the same distance as if it is the same distance towards x= 3.

For example, A (2,6). The height is the same, which means that x is only going to change, so y = 6. Reflecting on x = 3 is only a point away, this means that it should be A'=(4,6).

Do the same for all of the points, keeping in mind that y is the same because you are reflecting across the x- axis.

Hope this helps.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
