Find the measure of the acute or right angle formed by intersecting lines so that C can be mapped to C' using two reflections.
The rotation (2, y) + (-2, -y) maps C to C'.

1. evaluate 8x(2)y9(-2) for x=-1 and y=2 2. simplify the equation. -() 3. simplify the expression. [tex]\frac{5}{x(-2) y9(5)}[/tex]

3x + 4y = 5 x- 3y = -7 solve by substitution

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90
