Derive the equation of the parabola with a focus at (-5, 5) and a directrix of y= -1 Stumped :/

Solve the following simultaneous equation by using an algebraic method (either substitution or elimination) 2x + 3y=-4 4x-y=11

What is the range of the function? f(x)=-2|x+1|? a. all real numbers. b. all real numbers less than or equal to 0. c. all real numbers less than or equal to 1. d. all real numbers greater than or equal to 1

Wich statement could be used to explain why the function h(x)= x^3 has an inverse relation that is also a function
