I hope this helps you


x^2+2x+8=0


x^2+2x+1+7=0


(x+1)^2= -7


(x+1)^2= i^2.7


x+1= i.square root of 7


x=-1+ i.square root of 7

Which of the following compositions will map the red figure onto the blue figure?<br> 6lB<br> ATA
melisa1 [442]

Answer:

Point A is translated to A" by T(0, -6), since A has been shifted 6 units down

check the picture, the translated triangle is A"'B"'C"'.

clearly the angle between B"'A"' and B"A"' is 90 degrees, so we can complete the transformation by a 90° clockwise rotation or a 270° counterclockwise rotation.

from the choices given, we see that is is a 270° counterclockwise  rotation.

Answer: A.(o,-6). Ra,270

F + H ARE WRONG<br><br> HELP ME JIM!
RSB [31]
Reason F should be "CPCTC" which stands for "corresponding parts of congruent triangles are congruent". Its like saying "if two houses are identical, then the front doors should be the same". The houses in the analogy are the triangles, while the front doors are the corresponding parts. So if triangle DEC is congruent to triangle BEC, then the corresponding parts angle DEC and angle BEC are congruent.

===========================================

Reason H is "linear pair postulate" which says that if two angles form a linear pair then they are considered supplementary. This is simply what "supplementary" means. The two angles add to 180 degrees. A "linear pair" is where you have two angles that are adjacent and the angles combine to form a straight angle (180 degrees).

===========================================

Side note: It seems like some of this proof has been cut off. There should be more lines to this proof because the last line is always what you want to prove. In this case, the thing we want to prove is "angle DEC and angle BEC are right angles" so that should be the last statement.
