Answer:
sorry just came here for the points
Step-by-step explanation:
You can solve by using Pythagoras theorem.
Let the longest side be c.
a^2 + b^2 = c^2
If this holds, it is a right angle.
But, 3.5^2 + 4.5^2 is not equal to 5.5^2.
Photo please? and a function means that it cant have the same number of x axis'
example,
function;
15 6
-46 37
36 -37
27 -25
not a function;
-1 3
5 7
-5 6
-1 8
For example, the probability of an outcome of heads on the toss of a fair coin is ½ or 0.5. The probability of an event can also be expressed as a percentage (e.g., an outcome of heads on the toss of a fair coin is 50% likely) or as odds (e.g., the odds of heads on the toss of a fair coin is 1:1).
Answer:
Simplify the expression: 
Use the exponent power:
Apply the given rules;
Simplify:
then;
Therefore, the simplified expression of is,
