Set a is the set of all positive multiples of 2 that are less than or equal to 20. set b is the set of all positive multiples of 4 that are less than or equal to 20. how many elements are positive multiples of 4 that are less than or equal to 20, but are not positive multiples of 2?

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

Which of the following describes the graph of y--4x-36 compared to the parent square root function? stretched by a factor of 2, reflected over the x-axis, and translated 9 units right stretched by a factor of 2, reflected over the x-axis, and translated 9 units left stretched by a factor of 2, reflected over the y-axis, and translated 9 units right stretched by a factor of 2, reflected over the y-axis, and translated 9 units left save and exit next submit
