I can not see the drop-down menus, but here's the solution:

 $3+4d-14=15-5d-4d \\ -11 + 4d = 15 - 9d \\ 4d+9d=15+11 \\ 13d=26 \\ d=2$

-6x+y=-2 x-3y=9 what is the solution set?

Anarel [89]

Mult. the 2nd eqn by 6 and then add this "new" equation to the 1st given eqn:

-6x + y = -2
6x -18y = 54
--------------------
-17y = 52, or y = -52/17. Subst. this value of y into either equation to find the value of x.

Simplify the expression (2 square root sign 27) - (3 square root sign 32)

monitta

Answer:

$3\sqrt{3} - 4\sqrt{2}$

Step-by-step explanation:

The expression (2 square root sign 27) - (3 square root sign 32) is $2\sqrt{27} - 3\sqrt{32}$ .

To simplify, simplify inside the radicals by removing perfect square factors.

$\sqrt{27} =\sqrt{9*3} =3\sqrt{3}$

$\sqrt{32} =\sqrt{16*2} =4\sqrt{2}$

The expression becomes $3\sqrt{3} - 4\sqrt{2}$ .

This cannot be simplified anymore because whats under the radical is not the same.
