For what value(s) of x does y = 0 for the function tan(x)? -270°, -90°, 90°, and 270° -270°, -90°, 0°, 90°, and 270° -360°, -180°, 0°, 180°, and 360° -360°, 0° and 360°

So We Know That tan(x) Equals


We Can Use Logic, We Know That Anything That Makes The Denominator 0, Will Not Work, So We Need To Know What Makes Sin(x) equal to 0 and Cos(x) equal to 1 or -1 BUT NOT 0



We Didn't Want Cosine To equal Zero Because Then We Get



THE ANSWER IS C : -360°,-180°,0°,180°,360°

(6,-1)
Multiply each equation by the value that makes the coefficients of xx opposite.(−3)⋅(2x+6y)=(−3)(6)(-3)⋅(2x+6y)=(-3)(6)(2)⋅(3x−2y)=(2)(20)(2)⋅(3x-2y)=(2)(20)Simplify.−6x−18y=−18-6x-18y=-186x−4y=406x-4y=40Add the two equations together to eliminate xx from the system.Divide each term by −22-22 and simplify.Tap for more steps...y=−1y=-1Substitute the value found for yy into one of the original equations, then solve for xx.Tap for more steps...x=6x=6The solution to the independent system of equations can be represented as a point.(6,−1)
