Answer:
4(90) + 4(2)
Step-by-step explanation:
The given expression is 4(92)
This can be expressed as
This can also be expressed as
Using the distributive law of multiplication and additon,
a*(b+c) = a*b + a*c
In this case a=4
b=90 and c = 2
So the equivalent expression is
But this is the same as option 2 in the list of given options.
Hence the equivalent expression is 4(90) + 4(2)
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
