Josie bought 9 souvenirs during 3 days of vacation. After 4 days of vacation, how many total souvenirs will Josie have bought? Solve using unit rates.

Step-by-step explanation:

3 days =  9 souvenirs

That means, for each (1) day, Josie will have bought 3 souvenirs.

Essentially you're just multiplying by 3.

3 x 1 = 3

So, 3 x 4 = 12.

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'.
