Answer:

3 < x < 13

Step-by-step explanation:

<u>Triangle Inequality Theorem</u>

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Let x be the length of the unknown side.

Therefore, x will either be the longest side or one of the shorter sides.

Therefore:

   x < 5 + 8

⇒ x < 13

And:

   8 < 5 + x

⇒ 3 < x

So the range of possible values of the third side is <u>greater than 3</u> and <u>less than 13</u>:   3 < x < 13

"<br> Use the following graph to determine the solution(s) of:<br> y= x^2- x - 6
wariber [46]

Answer:

-2 and 3

Step-by-step explanation:

The x-intercepts or where the graph cuts the x-axis represents the zeros of y = x² - x - 6.

Thus, the zeros are -2 and 3. This is where the graph cuts the x-axis.

Therefore, the solutions of the graph are -2 and 3.

Find f(x) and g(x) so the function can be expressed as y = f(g(x)). y = Two divided by x squared. + 3
kodGreya [7K]
Hello,

g(x)=x²+3
f(x)=2/x
so f(g(x))=f(x²+3)=2/(x²+3)

Explainations:

f(y)=2/y
f(4y)=2/(4y)
f(x²)=2/x²
f(x²+3)=2/(x²+3)

Should the line of best-fit travel through the origin of the graph . Explain your reasoning
igomit [66]
No because if it does then you had no human error and based on what your graphing it is very unlikely that when you have zero at your x axis you will also reasonably be at zero on your y axis! Hope this helps you
