Which is the equation of an ellipse with directrices at x = ±4 and foci at (2, 0) and (−2, 0)?

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?
