Determine if the two lines with the given slope are parallel, perpendicular, or neither. Circle your
Sati [7]

Answer:

As the lines are neither parallel nor perpendicular.

Therefore, the correct answer is ''neither''.

Hence, option C is correct.

Step-by-step explanation:

Given

m₁ = 3/2

m₂ = -3/2

We know that when two lines are parallel, they have equal slopes

But

m₁ ≠ m₂

3/2 ≠ -3/2

As the m₁ and m₂ are not equal.

Hence, the lines are not parallel.

We know that when two lines are perpendicular, the product of their slopes is -1.

Let us check the product of two slopes m₁ and m₂

m₁ × m₂ = 3/2 × -3/2

              = -9/4

              = -2.25

As

m₁ × m₂ ≠ -1

Thus, the lines are not perpendicular.

Conclusion:

As the lines are neither parallel nor perpendicular.

Therefore, the correct answer is ''neither''.

Hence, option C is correct.

What is the answer to this: 1-n=7/12
Zanzabum
You can add, subtract, multiply, and divide things on both sides of the equation as long as you do the same thing to the other side so 
if i add n to this side 

1-n+n

i must add it to the other side 

1-n+n= 7/12 +n

1=7/12 + n 
 
 now you must subtract the 7/12 from both sides

1 - 7/12= 7/12 - 7 /12 + n 

5/12= n

hope this helps!
