3x - 5y = 20

(5; y)  -  put x = 5 to the equation

3 · 5 - 5y = 20
15 - 5y = 20  |-15
-5y = 5  |:(-5)
y = -1

Answer: (5; -1)

(x; 2)  -  put y = 2 to the equation

3x - 5 · 2 = 20
3x - 10 = 20    |+10
3x = 30    |:3
x = 10

Answer: (10; 2)

Find the volume of the prism.<br><br> 5 units<br> 2 units<br> 8 units
Deffense [45]

Answer:

80 units.

Step-by-step explanation:

If it is a rectangular prism, then it is 5×2×8, which is 10, from the 5×2 and 8. 10×8 is 80. So the final answer is 80 units cubed. Hope this helps! If you are still confused, please comment so I can help you!

The equation of line k is y=
Nina [5.8K]

Answer:

Neither parallel nor perpendicular

Step-by-step explanation:

I'm assuming you meant line k is y = 3x -2. If not, this is wrong.

For this, you need to put both lines in point-slope form, or the form that line k is already in. This means you only need to convert line m.

-2r + 6v = 18

6v = 2r + 18

v = 2/6r + 18/6

v = 1/3r + 3

Now you can answer the question.

To be parallel, lines must have the same slope (but a different y-intercept). 3 and 1/3 are not the same, so the lines are not parallel.

To be perpendicular, one line must have the opposite reciprocal (fraction flipped and + goes to - or - to +) of the other. While 3 is the reciprocal of 1/3, they are both positive, so they are not perpendicular.

To be the same line, the equations must be absolutely identical, which they aren't.

This leaves the last option: neither.

Let me know if you need a more in-depth explanation of anything here! I'm happy to help!
