If AB = 3x + 5, BC = 2x + 8, and AC = 88, what is the value of x?

25 ! the line of best fit is h = 5a + 86. predict the height at age 16.

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.
