Answer:

8 and 9

Step-by-step explanation:

The triangle inequality states that the sum of the two shortest sides must be greater than the longest side.

Let's check the first one. 5 + 8 > 13 → 13 > 13 which is false.

6 + 7 > 13 → 13 > 13 which is false.

7 + 2 > 13 → 9 > 13 which is false.

8 + 9 > 13 → 17 > 13 which is true.

tiny-mole [99]

Answer:

The y intercept is 3

Step-by-step explanation: The y interception ocurrs when X=0,so in the x,y pais you have (0,3), indicating that when X=0, Y=3. Also, according to the information, the linear equation would be: y=mx+b being m=slope and b the interception of the y axis, so the equation would be: y =-3x+3.
