8. Find the congruence transformation that maps ∆ABC to ∆A’B’C’. Explain your reasoning

tino4ka555 [31]

In this case, to flip any of the points to map up accurately to the other points, we would have to do a transformation of reflection about the y-axis. The reason behind this is that out of other transformation process, we can only achieve the image of triangle ∆A’B’C’ through reflection.

Dilation will not work since it only changes the size of the object. The shape and position will not affected.

A translation will not work because although the shape can move, it still needs to flip to achieve triangle ∆A’B’C’.

A rotation will also not work because when you rotate it, the shape will still not map over the new one.

Referees of high school soccer games will end a game at half time if a team is ahead or behind by at least 8 goals. During the d

slavikrds [6]

If at the end of the first half, the difference between the goals scored by the applewood team and the opposing team is greater than or equal to 8, then the referee will finish the game at the end of the first half.

If we call g the number of goals scored by the opposing team, then we can express this situation as an inequality:

$11-g \geq 8\\g \leq 11-8\\g \leq 3$

However, it is impossible for a team to score -1 goal. Therefore the number of goals scored by the opposing team must be a number greater than 0.

So, the inequality is:

$g \leq 3$ and $g \geq 0$

$0 \leq g \leq 3$

The attached figure shows the graph for this inequality, which represents the number of goals that the opposing team could score if the referee finished the game in the first half.

How do you solve 125 - (5-9)^3÷2

hoa [83]

Solve what is in parenthesis first (5-9) = -4

Solve exponents next -4^3 = -64

Divide next
$- 64 \div 2$
= -32

Lastly, subtract and resolve the negatives which become a positive number 125 - (-32) = 125 + 32 = 157
