Need help on the following problems please:

1.Evaluate 4lxl + 5lyl given that x = 8 and y = -7

2.Evaluate (7x - 11y)/7 given that x = 8 and y = 3

3.B = {18,(sqr root "radical symbol)6, -11, 0, 0/3, 0.33, -6n, 0.999...}. List all the elements of B that are irrational numbers.

4.Fill in the blank with the correct inequality symbol. If x < 6, then -3x _ -18.

5.solve the rational equation (4x-1)/(2x+3)=(6x+8)/(3x-4)

6.Solve x2 (note: x2 = squared symbol) - 2x - 24 = 0 by using completing the square.

7.A bank loaned out $70,000, part of it at the rate of 12% per year and the rest at a rate of 6% per year. If the interest received was $5760, how much was loaned at 12%?

8. Solve the rational equation x/(x-1)+6=1/(x-1)

9. Write 17x + 3y =10 in slope intercept form.

10. Find the general form of the equation for the line with slope = - 2/3 and containing the point (0, 4).

11. Find an equation for the line that is perpendicular to the line 3x - y = 6 and contains the point (0, 2).
