A triangle should have 3 points and 3 sides. Let say that the point is ABC. Then the sides would be AB, AC and BC.
There are 3 strings with a different length that can be put into the sides. Assuming the string can be used once, then the possible way would be:
3!/(1+3-3)!= 3!/1!= 3*2*1= 6 ways
The y-coordinate of point T would be -4.5 the whole ordered paid would be (-3,-4.5).
Answer:
The answer is C
Step-by-step explanation:
We have f(x) function as below:

and the converted function g(x) is as mentioned below:

We can observe that:
f(x)=-g(x)
Therefore it can be said that this function reflected horizontally.
Note: please check the plot attached.
Subtract 89 from -42. k=-131
