Given that Uo=-3 find U1 and U2

If the speed of an electromagnetic wave is 100,000 cm/s and its wavelength is 100 cm, what is its frequency? a) 100,000 cycles per second (hz) b) 1 × 10-3 cycles per second (hz) c) 10,000,000 cycles per second (hz) d) 1,000 cycles per second (hz)

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

Solve the equation by completing the square. x^2+2x=17
