A.  (-3,0)

Add the two equations together so one variable is eliminated:

  5x + 2y = -15

+  2x - 2y = -6

-------------------------

   7x         = -21

7x = -21

Solve for x:

x = -21 ÷ 7

x = -3

Now substitute x to any of the equation to solve for y. (I'll choose the second equation):

2x - 2y = -6

2(-3) - 2y = -6

-6 - 2y = -6

-2y = -6 + 6

-2y = 0

y = 0

x = -3

y = 0

(-3,0)

Why do you think that the Amazons were featured so prominently in Greek myths and legends?
hram777 [196]

Answer:

I think the Amazons were featured so prominently in Greek myths and legends because they had to do with the Greek Gods, especially Zeus. Zeus and Queen Hipolyta gave birth to Princess Diana. I believe Athena and Artemis honor them because they are female warriors. Also Hercules went to their island to get the Queen's belt as a task from Hera.
