3/5 + 1/5 pls help meee

Which expression is equivalent to the expression shown?

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 solution(s) to the system of equations. select all that apply y=x^2-1 y=2x-2
