Answer:
m=-1
Step-by-step explanation:
9m+13 =4
Subtract 13 from each side
9m+13-13 =4-13
9m = -9
Divide each side by 9
9m/9 = -9/9
m = -1
Answer: 
Step-by-step explanation:
You know that the given function is:

You know that you must evaluate this function for
.
Then, to evaluate the function for
, you need to substitute this value into the given function and simplify it.
Therefore, you get:

So, the answer is: 
- Triangle Inequality Theorem: States that the sum of any two sides of a triangle is greater than the length of the third side;

So for this, we are applying the triangle inequality theorem. If any of the inequalities are not true, then this cannot be a triangle. (Let A = 7.7, B = 4.0, and C = 1.7)

<u>Since the second inequality is false, these lengths cannot form a triangle.</u>
Eight divided by two times (5 plus 5)
