Evaluate each expression if x= 3, y= 12, and z = 8

4z +8-6

Which graph corresponds to the function f(x) = x2 + 4x – 1?

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′?

Can someone me with this? i’m not sure what to put for my equations.
