What is the length of segment EB in parallelogram ABCD ?

F(x)=x/2-2 and g(x)=2x^2+x-3 find (f+g)(x)

Two line segments are shown in the figure below. suppose that the length of the line along the x-axis is 6, and the length of the hypotenuse of the triangle is 10. what is the equation of the hypotenuse line (shown in red, below)?

Find the solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
