Answers? ? i cant seem to find out what number is representing the shapes

The shapes are being used instead of variables.

For problem 4; start with clue 2, then clue 3, then clue 4, and lastly do clue 4.

Clue 2

3 · square - 8 = 19

3 · square = 27 added 8 to both sides

square = 9 divided both sides by 3

Clue 3

2 · triangle + 3 = -3

2 · triangle = -6 subtracted 3 from both sides

triangle = -3 divided both sides by 2

Clue 4

square + triangle = 6

(9) + (-3) = 6 substituted solutions from Clue 2 and Clue 3

6 = 6 True statement confirms that Clues 2 & 3 are correct

Clue 1

star + square = 12

star + (9) = 12 substituted solution from Clue 2

star = 3 subtracted 9 from both sides

triangle = -3, star = 3, square = 9

For problem 5; do the same thing as problem 4 and start with Clue 2

Answers: triangle = -2, star = 10, square = 8

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'.

it is only things thain can be deafeated
