Find the points which defined the reflection of the figure giving by A(2,2) B (3,7) C (5,5) reflected across the X-axis
elixir [45]

well the formula to reflecting across the x-axis is (x,-y).so the final points are A'(2,-2)   B'(3,-7)  C(5,-5) ANSWER



additional information

By the way the -y in the formula does not mean every number will always be negative it means switch the sign  so if the point is (5,-7) than reflecting across the x-axis it would be (5,7)

Alchen [17]

Answer:

There were 2747 yes votes.

Step-by-step explanation:

This question can be solved using proportions.

The ratio of yes votes to no votes was 5 to 3 .

This means that for each 5 + 3 = 8 votes, 5 were yes and 3 were no.

If there were 4395 total votes, how many yes votes were there?

For each 8 votes, we have 5 yes. How many yes votes were there in 4395 votes?

5 yes - 8 votes

x yes - 4395 votes

8x = 4395*5

x = 4395*5/8

x = 2747

There were 2747 yes votes.
