Answer:
Option A. These two lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
step 1
Convert the given equation A in slope intercept form
where
m is the slope
b is the y-intercept
we have
----> equation A
Solve for y
That means----> isolate the variable y
Divide by 3 both sides
so
step 2
Convert the given equation B in slope intercept form
where
m is the slope
b is the y-intercept
we have
----> equation B
Solve for y
That means----> isolate the variable y
subtract 3x both sides
Divide by 2 both sides
so
step 3
Compare the slopes
The slopes are opposite reciprocal (the product is equal to -1)
therefore
These two lines are perpendicular
Answer:
Graph A is the correct choice.
Step-by-step explanation:
Let x be the number of weeks.
We have been given that a semiconductor manufacturing company employs 1,000 people. The average weekly salary of each employee is $750.
Let us find the weekly salary for 1000 employees by multiplying 1000 by $750.
Let us find amount of salaries after 52 weeks as 1 year equals 52 weeks.
Since at week 0, the salaries for 1000 employees will be also 0, so point (0,0) will be on the line of our graph.
Now let see which of our given graphs has point (0,0) and (52,39000000).
We can see that graph A has y-value 39 million on x equals 52, therefore, Graph A is the correct choice.
