Jackie got (4, -2) as her solution to a linear system. She was checking the solution in the first equation, 2x - y = 6. She decided that (4, -2) did work in that equation, and she was getting ready to check the second equations. Her friend was doing the same problem and told Jackie she had made an error when doing the check. The friend is correct. What mistake did Jackie most likely make that would cause her to think (4, -2) was the solution? <3 Thank you

Which expression is equivalent to 5r6141 2r+st6

Determine whether the following statements are true and give an explanation or counterexample. bold a. when using the shell method, the axis of the cylindrical shells is parallel to the axis of revolution. bold b. if a region is revolved about the y-axis, then the shell method must be used. bold c. if a region is revolved about the x-axis, then in principle it is possible to use the disk/washer method and integrate with respect to x or the shell method and integrate with respect to y.

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f - g)(x). a. (f-g)(x) = x + 15 o o b. (f- g)(x) = -x - 15 o c. (f- g)(x) = 5x + 3 o d. (f- g)(x) = -x+3 submit
