Type the correct answer in each box. Spell all words correctly. A sequence of transformations maps ∆ABC onto ∆A″B″C″. The type o
f transformation that maps ∆ABC onto ∆A′B′C′ is a . When ∆A′B′C′ is reflected across the line x = -2 to form ∆A″B″C″, vertex of ∆A″B″C″ will have the same coordinates as B′.

Answer:
A) Reflection
B) (-2,-6)
Step-by-step explanation:
Have a look at the attached picture:
The type of transformation that maps ∆ABC onto ∆A′B′C′ is a reflection across the x-axis. A reflection is an isometry, which means the original(pre-image) and image are congruent, that can be described as a "flip".
When ΔA'B'C' is reflected across the line x = -2 to form ΔA"B"C", the vertex of ΔA"B"C" will have the same coordinates as B' which is (-2,-6) ....

Answer:
7
Step-by-step explanation:
Just notice that correct answers are whole numbers.
And, to win the game,Maria must have a score less than -80, it means she needs to score al least -85 ( it can not be -81, -82.. because 1 correct answer score -5, only multiples of -5 are accepted)
So, we take: = 7 correct answers to win the game.
Hope it will find you well.
