Given the following system of equations:
2x + 6y = 12
4x + 3y = 15
which action creates an equivalent system that will eliminate one variable when they are combined?
multiply the second equation by −2 to get −8x − 6y = −30.
multiply the first equation by 2 to get 4x + 12y = 24.
multiply the second equation by −4 to get −16x − 12y = −60.
multiply the first equation by −4 to get −8x − 24y = −48.

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.

Assume that there is a 11% rate of disk drive failure in a year. a. if all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive? b. if copies of all your computer data are stored on four independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
