Se considera numerele rationale a, b,c, d direct proportionale cu 5,4,2,3.Stiind ca bc=4d, determinati multimea divizorilor numarului a+b+c+d.

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 power set of each of these sets, where a and b are distinct elements. a) {a} b) {a, b} c) {1, 2, 3, 4} show steps

Which graph shows the solution to the system of linear inequalities? y-4t< 4 y
