\left(\mathrm{Decimal:\quad }x=-0.75\right)
hope it helps :P
3x + 4 = x+ 8 > 3x - x = 2x > 2x + 4 = 8 > 8 - 4 = 4 > 2x / 2 crosses out > 4 / 2 = 2 > x=2
2y + 5 = y + 7 > 2y - y = y > y+ 5 = 7 > 7-5= 2 > y=2
the perimeter of the kite is 4
Vertical angles are equal, which is similar to saying "vertical angles are congruent." Note: vertical, not verticle.
Given:
The point is (-5,7).
To find:
The image of the given point after 90 degrees counter clockwise rotation.
Solution:
If a point rotated 90 degrees counter clockwise, then

Let the given point is P(-5,7). Using the above rule, we get

Therefore, the image of the given point after 90 degrees counter clockwise rotation is (-7,-5).
