Is the following equation proportional or non-proportional? y = 2x + 1

Let w=23 . what is the value of w + 45 ?

Brainlest answer can you find the area and circumference of a circle given the radius or diameter? if its yes or no explain why

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.
