Answer:

1) x=3, y=-3

Step-by-step explanation:

10x + 7y = 9 —— (1)

-4x -7y = 9 —— (2)

(1) + (2)

6x = 18

x = 18/6

x = 3

put x=3 in (1)

10(3) + 7y = 9

30 + 7y = 9

7y = 9 - 30

7y = -21

y = -21/7

y = -3

Answer and Step-by-step explanation:

Yes, the three side lengths could form a triangle.

To find out if the sides can form a triangle, you take the lowest side lengths and add them together. If they are <u>greater </u>than the longest side, then they can form a triangle. <u>If it is equal or less than the longest side,</u> then it CAN NOT form a triangle.

7.8 + 10.4 > 13

18.2 > 13

<u>So, the answer is Yes.</u>
