Answer:
.43
Step-by-step explanation:
Answer: 1)
y < 0
x >= 0
2)
3x - 4y < 1
3x - 4y < 8
3) 4x + y > 4
8x + 2y < -5
4)
3x - y > 1
6x - 2y < 20
Step-by-step explanation:
In order to find out the association, you need to plot the data. Given that m is x, and n is y, after plotting, the graph shows a positive linear association. The graph rises from left to right. So the answer is letter D.
Answer:
The answer is below
Step-by-step explanation:
The general form of a line is given by:
Ax + By + C = 0
The slope intercept form of a line is give by:
y = mx + b;
where m is the slope and b is the y intercept
Given a line with equation Ax + By + C = 0; the slope of the line can be gotten by representing in slope intercept form, hence it becomes:
By = -Ax - C
y = (-A/B)x - C/B
The slope is -A/B
For a line with equation Bx - Ay + C = 0:
Ay = Bx + C
y = (B/A)x + C/A
the slope is B/A
Two lines are said to be perpendicular if the product of the slopes is -1. Hence:
-A/B * B/A = -1; hence the two lines are perpendicular
