Graph the image of triangle ABC after a reflection across the x-axis. The vertices of the image will be called A” B” , and C” .

For what values of the variable x is the expression square root of 7x+14+ square root of 7-x a real number?

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.

Marco states that 7.696696669…… is a rational number because it is a repeating decimal. is he correct? justify your answer.
