An event occurs in system k' at x' = 2 m, y' = 3.2 m, z' = 3.2 m, and t' = 0. System k' and k have their axes coincident at t = t' = 0, and system k' travels along the x axis of system k with a speed 0.76c. What are the coordinates of the event in system k?

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
