Alright, he you go:

Using the rule,

a + b > c

Where a, b, and c are any of the three sides of a triangle, we have three inequalities.

5 + 8 > x

5 + x > 8

8 + x > 5

The first one is x < 13

The second one is x > 3

The third one is x > -3

So the interval of x is 3 < x < 13

Assuming that the question is asking for the possible integer, we have:

4, 5, 6, 7, 8, 9, 10, 11, and 12.

For the second one...using this tool :

https://www.graphpad.com/quickcalcs/linear2/

The line fo best fit has the equation

Y = 1.040*X + 5.210

The slope is 1.040

Third one...this is ust the graph of y = -3x^2 shifted down 6 units

The vertex of y = -3x^2 is at (0,0)

So...the vertex of this function is (0,-6)

So...the y value of the vertx is -6
