The triangles shown are similar. Which is an appropriate similarity statement for the triangles?

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 the following pair of equations for x and y: ax/b_ by /a= a +b; ax - by = 2ab

Math i have no idea how to do a and b
