Answer: 25

Step-by-step explanation: 8*5=40, so multiply 5 by 5. Or, to put it another way:

5/8 = 25/40

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!

Graph the line with slope 7 and y-intercept -7
poizon [28]

<u>Given</u><u> </u><u>:</u><u>-</u>

  • To graph the line with slope 7 and y intercept -7.

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The graph of the line .

<u>Solution</u><u> </u><u>:</u><u>-</u>

Here since the slope of the line is 7 and y intercept is -7 , we can use the slope intercept form of the line to find the equation of the line . The slope intercept form of the line is ,

\longrightarrow y = mx + c

On putting the respective values ,

\longrightarrow y = 7(x) + (-7)

\longrightarrow y = 7x - 7

<u>For</u><u> </u><u>the</u><u> </u><u>graph</u><u> </u><u>see </u><u>attachment</u><u> </u><u>.</u>

Answer:

a+b+c = 180

48+59+b=180

107+b=180

b=180-107
