Answer:
Last one
Step-by-step explanation:
To solve this question all you have to do is input the X and y coordinates and test each point in the question. To see which of those points. Have the left hand side equal to the right hand side after doing all of the operations.
Answer:
m= 1/4
Step-by-step explanation:
tried helping I don't know if this is the right way to do it for you
Two lines are perpendicular if and only if the product of their slopes is - 1.
So, you just need to find the slope of each line and find out the product of their slopes.
I will do one example for you.
L1: y = 3x + 5
L2: y = - 3x + 14
L3: y = -x/3 + 14
The slope of a line is the coefficient of the x.
So the slopes are:
L1: slope 3
L2: slope -3
L3: slope -1/3
So now multiply the slopes of each pair of lines:
L1 and L2: 3 * (-3) = - 9 => No, they are not perpendicular
L2 and L3: (-3) * (-1/3) = 1 => No, they are not perpendicular
L1 and L3: (3) * (-1/3) = -1 => Yes, they are penpendicular.
nonsense because, 6 ≠ 12
Step-by-step explanation:
(15 - 6) - 3 = 15 - (6 - 3)
you gotta to the parentheses first.
9 - 3 = 15 - 3
6 = 12
6 ≠ 12
