Step-by-step explanation:
1. If you are trying to find a linear equation from those two points, use the equation y2-y1 over x2-x1. y2-y1 just means the second point's y coordinate minus the first point's y coordinate (same goes for x2-x1).
2. So if you were to plug the coordinates into the equation, it would be: -8-8 over 8-(-1).
3. Solve to get -16/9 because -8-8=-16 and 8-(-1)=9, so -16/9. -16/9 is the slope of the line in the y=mx +b equation.
4. It would be written like y=-16/9x +b
5. Now we need to find b which is the y-intercept. To find this pick one of the points (we'll just do (-1,8)), and plug in the x and y coordinates and solve for b.
- 8=-16/9(-1) +b
- multiply -16/9 by -1 which is 16/9
- subtract from both sides for it to be 8-16/9 on the left side which is 6 2/9, and that is b
6. The complete equation is now y=-16/9x + 6 2/9
The vertex is the center point of the line or the axis of symmetry
So your answer should be (-2, -5)
Answer: 135%
Step-by-step explanation: Given
Europe = 35%
Asia = 10%
Australia* = 20%
North America = ?
To find
Europe + Asia + Australia =
35% + 10% + 20% = 65%
Then the total subtracted from the given
200 - 65 = 135
Therefore,
North America = 135%
Confirm
To make sure that is the correct answer, add it all together.
35 + 10 + 20 + 135 = 200
Which means it is correct.
In mathematics: Arithmetic progression, sequence of numbers such that the difference of any two successive members of the sequence is a constant. Geometric progression, sequence of numbers such that the quotient of any two successive members of the sequence is a constant. so i chose b)Sequences
