If the sin 0° = 0, then which statement is true? a cos 90° = 1, because the cosine and sine are complements
b cos 180° = 1, because the cosine and sine are supplements
c cos 90° = 0, because the cosine and sine are complements
d cos 180° = 0, because the cosine and sine are supplements

Write the expression in simplified radical form. show all steps and work including any foil method work. (hint: use the conjugate. no decimal answers.) (9-2√3)/(12+√3)

How do you solving the solution of each system using elimination?

The description below represents function a and the table represents function b: function a the function is 5 more than 3 times x. function b x y −1 2 0 5 1 8 which statement is correct about the slope and y-intercept of the two functions? (1 point) their slopes are equal but y-intercepts are not equal. their slopes are not equal but y-intercepts are equal. both slopes and y intercepts are equal. neither slopes nor y-intercepts are equal.
