Place the digits from 1 to 9 into the circles so that the sum of the numbers in each straight line is the same

What values of c and d make the equation true?

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.

If you could answer these your a life saver
