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.

Look at the picture and read the question. I think the answer is 137 degrees but I don't know how to get it. I need help lol. Th
slamgirl [31]

Answer:

That is a parallelogram so that opposite angles are equal.

10x -27  = 2x + 29

x = 7

and therefore those angles equal 43 degrees each

It is a parallelogram, so

angle V + W +X + Z = 360

we know that angle Y + angle W = 2 * 43 = 86 degrees

angle V + angle X = 360 -86 degrees

angle V + angle X = 274 degrees

angle V = 274 / 2 = 137 degrees

    We need to calculate a TIME.  Here, TIME = job / rate

Here, 

             1 JOB                                      1                 1
------------------------------------- = ------------------ = ---------------
   JOB/5 min + JOB/15 min           1/5 + 1/15     3/15+1/15
           1
= ------------ minutes = 15/4 minutes = 3 3/4 minutes (answer)
