Whats the anwser for 16x−7≤−71 i suck at this

In the figure shown below, m < 40 and ab =8. which equation could be used to find x?

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.

Hi, can anyone show me how to do this problem? 100 points for this. in advance
