Answer: D.

If you substitute the x = 9 into the first equation it will look like this:
2y = (9) - 6
Then solve for y,
2y = 3
y = 3/2

Therefore, the correct answer would be D. (9, 3/2)
This is because ordered pairs are (x,y) and x = 9 and y = 3/2

I hope this helps!!

Roth IRA doesn't get you a tax deduction for the contributions, but the earnings grow tax free and you don't pay tax on the withdrawals after retirement. A traditional IRA gives you a tax deduction for the contributions at the time you make them, and the earnings grow tax free, but when you withdraw the money after retirement, you are taxed on it. The idea is that you are hopefully in a lower tax bracket at that point. So its only natural that Roth IRA is the best.

setting it up looks like this

tan 72° = $\frac{x}{8\\}$
