With questions like this (to see if theyre parallel), all you have to do is see if lines have a congruent slope. if yes (ex: 2 and 2), then they are parallel. if the slopes are opposites (ex: 4 and -1/4), then they are perpendicular. If they have no such relation (ex: -3 and 1/7), then they are neither.
with this problem, find the slope by separating the same variable in each equations, like this:
2x + 7y = 6
-2x -2x
7y = -2x + 6
(the second equation is already separated) so now we have
7y = -2x + 6 and 7y = 2x + 6
since -2 does NOT equal 2, these two graphs/lines are NOT parallel.

Answer:
16
Step-by-step explanation:
You can prove this by taking 16 and dividing it by 2, and you will see that the answer is 8

Look at the picture.
the length of horizontal segment: |10 - 4| = |6| = 6
the length of vertical segment: |8 - 3| = |5| = 5
Use the Pythagorean thorem:
Answer:
If it is using pi as 3.14, it is 56.52.
If it is just the pi symbol, it is 18π.
Step-by-step explanation:
We do 9 x 3.14 = 28.26 and then you multiply that by 2 to get 56.52.
We do 9 x π = 9π. Then multiply by 2 to get 18π.
Nothing. Say that you substitute 3 for 'z.' 6(3) is the same as (3)6. Simple.
