The sum of two positive integers, a and b, is at least 30. The difference of the two integers is at least 10. If b is the greater
integer, which system of inequalities could represent the values of a and b?
O a + b 230b2a + 10
a + b 2 30 bsa - 10
a+bs 30 b2a + 10
a+bs 30 bsa - 10

Which number produces a rationale number when multiplied by 1/5

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.

Marcus and cody both leave the park at the same time, but in opposite directions. if cody travels 6 mph faster than marcus and after 4 hours they are 64 miles apart, how fast is each traveling? solve using rare times time = distance.
