The expression shown in the model should be 2x² +1x. This is because 1x2 + 1x2 = 1

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

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.

If julia has a value of x5.4 that is equivalent to x10.9 true or false. explain
