Answer:
The answer is below
Step-by-step explanation:
The slope of a line (m) is given by:
Two lines are parallel if they have the same slope and perpendicular if the product of their slope is -1.
1)
Since the product of their slope is -1, they are perpendicular
2)
Since the slope is not the same or product of their slope is not -1, they are neither parallel or perpendicular
3)
Since the slopes are the same, they are parallel
4)
Since the slopes are the same, they are parallel
5)
Since the product of their slope is -1, they are perpendicular
The value of p if the pair of equations may have one root common is 1.
<h3>What are the roots of the equation?</h3>Let the equation be ax² + bx + c = 0.
Then the roots of the equation will be
The equations are given below.
2x² + px - 1 = 0 and 3x² - 2x - 5 = 0
The roots of the equation 3x² - 2x - 5 = 0 will be
3x² - 5x + 3x - 5 = 0
(3x - 5)(x + 1) = 0
x = -1, 5/3
At x = -1, the value of p will be
2(-1)² + p(-1) - 1 = 0
2 - p - 1 = 0
p = 1
The value of p if the pair of equations may have one root common is 1.
