The equation x2 – 1x – 90 = 0 has solutions {a, b}. what is a + b?

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.

A. what does the point (4, 122) represent? b. what is the unit rate? c. what is the cost of buying 10 tickets?
