<u>Answer:</u>
The coordinates of point C' are (4, -2)
<u>here's why:</u>
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y). So if we use this information with the original coordinates, (-4, -2), the new coordinates will be (4, -2).

General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
5x - (x + 4) + 1 = 3 - 2(x + 6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 5x - x - 4 + 1 = 3 - 2x - 12
- Combine like terms: 4x - 3 = -2x - 9
- Add 2x on both sides: 6x - 3 = -9
- Add 3 to both sides: 6x = -6
- Divide both sides by 6: x = -1
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 5(-1) - (-1 + 4) + 1 = 3 - 2(-1 + 6)
- Parenthesis (Add): 5(-1) - 3 + 1 = 3 - 2(5)
- Multiply: -5 - 3 + 1 = 3 - 10
- Subtract: -8 + 1 = -7
- Add: -7 = -7
Answer:
Total number of ways will be 
Step-by-step explanation:
We have to select 7 countries
3 countries selected from a block of 54
So number of ways of selecting these three countries 
Now 1 country is selected from 66 block
So number of ways to select 1 country = 
Now next 3 country is selected from 69 country
So 
So total number of ways to select 7 countries = 24804×65×52394
