Answer:
The 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)
we have
----> equation A
isolate the variable y
Divide by 7 both sides

The slope of the line A is 
----> equation B
isolate the variable y
Divide by 3 both sides

The slope of the line B is 
Compare the slope of both lines


so
----> the lines are not parallel
Find the product of the slopes
----> the lines are perpendicular
Answer:
The answer would be -10x-9
Answer:
Your answer is A.
Step-by-step explanation:
If you take the Cords of 'A' and make them both negative you will find your answer.
Answer:
3.07091228=x
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp/ adj
tan 21 = x/8
8 tan 21 =x
3.07091228=x
Answer:
D. 32 ft^2
Step-by-step explanation:
You find the mean of the two bases 7+9= 16 16/2=8 Then multiply 8 by 4 to get 32 ft ^2
