Antonio is starring in the high school play and has lots of family members and friends who want to see him perform. He has purchased 17 tickets for the
play. Some of these are adult tickets and some are child tickets. The cost of an
adult ticket is $4 and the cost of a child ticket is $2. If the total cost of the 17
tickets was $60, find the number of each type of ticket purchased.

12 Kids 9 Adults

Step-by-step explanation:

12 x 2 = 24   < Kids

9 x 4 = 36  < Adults

  24

+ 36

= 60

there is no image or shapes attacted

step-by-step explanation:

for the friend request.

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'.
