Solve the exponential equations: 2^3x =11

Find the solution of this system of equation -7x+y=-20 9x-3y=36

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.

Solve each quadratic equation by factoring and using the zero product property. n^2 - 49 = 0
