Find formulas for x, y, and z in terms of a, b, and c. it may be necessary to make assumptions about the size of a matrix in order to produce a formula.

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

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

Find the distance between (7,-6) and (-3,-9)
