Consider the systems of equations: y=4/5 x−3

y=4/5 x+1

Without graphing, determine and explain how many solutions you would expect this system of equations to have.

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′?

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?

What is the value of the discriminant, b2 ? 4ac, for the quadratic equation 0 = x2 ? 4x + 5, and what does it mean about the number of real solutions the equation has?
