Answer:
To create a line plot with a cluster around 6-8, you basically just group a lot of dots around the area (such as putting 4 dots over the dashes labelled 6-8). And for a gap between 4-5, just put one dot over 0-3.
All triangles = 180 degree
Angle 1 + angle 2 + angle 3 = 180
44 + 79 + angle 3 = 180
123 + angle 3 = 180
Angle 3 = 57

The solution to the equation 3 and 4 by elimination is x = -2 and y = -2
<h3>Simultaneous equation</h3>
2x = 3y + 2. (1)
3x = 5y + 4. (2)
2x - 3y = 2. (3)
3x - 5y = 4 (4)
- Multiply (3) by 3 and (4) by 2
6x - 9y = 6. (5)
6x - 10y = 8. (6)
- subtract (5) from (6) to eliminate x
-10y - (-9y) = 8 - 6
-10y + 9y = 2
-y = 2
y = -2
- substitute y = -2 into (3)
2x - 3y = 2. (3)
2x - 3(-2) = 2
2x + 6 = 2
2x = 2 - 6
2x = - 4
x = -4/2
x = -2
