Answer: Second, Fourth and Fifth options are correct.
Step-by-step explanation:
F is the incenter because F is the point of intersection of the three angle bisector of the triangle.
As we can see that the angle bisector divides the angles into equal angles.
So, F is the point of concurrency of the angle bisectors of the angle of the triangle.
F is equidistant from the three sides of the triangle.
Hence, Second ,Fourth, Fifth options are correct.
1. Y= 4/7x-2
2. Y=-3/4x+6
3. Y=9/2x+18
54-59=-5
If the smaller number is on the left, it will be a negative answer in cases of addition.
The answer is c because 19-27 is equal to 19+(-27)
To figure this out use keep change change
Keep the original sign of the first # (19) then make the sign it’s opposite (- =+) then change the sign of the next # (27= -27)
