Which ordered pair is a solution of this

2 answers:

8 0

The answer is (-1,-2)

First, we put the equation in standard form
Add the 2x to the other side leaving us with -y = 2x +4. They y must be positive so we multiply the whole equation by -1. This gives us y = -2x - 4. We then plug the coordinates in to find out which one comes out to be true.

The only one that comes out true is (-1,-2)
-2 = -2(-1) - 4 which comes out to -2 = -2 True.

Simplify (12y^7/18y^-3) assume Y=0

iren2701 [21]

$\dfrac{12y^7}{18y^{-3}} = \dfrac{2y^{7+3}}{3} = \dfrac{2y^{10}}{3} = \dfrac{2}{3}y^{10}$

2 divided by 1 and 6/7

ale4655 [162]

This problem, as written, requires a bit of guessing regarding your intentions. My interpretation is that you want to do this division:

----------

1 6/7

If that's correct, here's what to do: rewrite 1 6/7 as 13/7 (an improper fraction).

Then divide:

-------- This is equivalent to the multiplication (2/1)(7/13) = 14/13 (answer)

13/7
