At the school bookstore, quinn purchased a binder for $4.75 and 4 pens for $0.79 each. what was quinn's total cost

Quinn's total cost was $7.91.

Step-by-step explanation:

You already know the binder is $4.75 so that remains the same.

You have to find the total cost for all the 4 pens:

$0.79

x      4

$3.16

Add up the cost of the binder w/ the cost of the 4 pens:

$4.75

+

$3.16

$7.91

➴ Hope this helps!

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
