What pair of numbers has a sum of 1 and a difference of 9? x y x + y = 1

x y x - y = 9

(if f(x)=4x^2 and g(x)=x+1, find (f o g)(x)

Solve this and show you’re work step by step ! -5 3/4+3h< 9 1/4 -

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′?
