Okay so what you want to do is since it is asking to combine like terms you would take the -m and add a positive m so: -m+m=0

  So since we did it to one side we have to do it to the other and 3m plus another m would come out to a total of 4m. So now our equation should look like this: 6=4m+14

  Now what you want to do is take away 14 from the right side to cancel it out, so, 14-14=0 Now that we've canceled that out we have to take 14 away from 6. Which 6-14 comes out to be -8. So now the problem should be -8=4m.

  Alright now all that's left to do is to isolate the variable and find out what m is. So to do this you want to divide both sides by 4 so, -8÷4 and 4m÷4. Know -8 divided by 4 is -2, and for 4m divided by 4 the fours are going to cancel out leaving us left with the m.

So know all that's left is: -2=m

Therefore m = -2

Which values of k would cause this system of equations to have no solution? Check all that apply.
xeze [42]

Answer:

x= -2y/3

-4y+4y=14

0y= 14

This has no solution.

Step-by-step explanation:

Answer In cases of two equations having two unknown variables the simultaneous method of solving the equations is adopted.

Supposing “0” as the value of “k” we will have the equation as 3x+2y=0

Then separating variable x will give, x= -2y/3

Substituting the value of x into the first equation that is: 6x + 4y = 14

6(-2y/3)+4y=14

Expanding this we get: 6(-2y/3)+4y=14

-4y+4y=14

0y= 14

Thus, no solution.

(3/5) cubed Please explain to me how you would do this

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷  It would be done in the same way it would if it was an integer ;

think of it as two separate parts

(3/5)^3 = 3/5 * 3/5 * 3/5

Calculate the top half, then the bottom half and put them together

3 * 3 * 3 = 27

5 * 5 * 5 = 125

Thus, your answer will be 27/125

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Find the angle between the given vectors to the nearest tenth of a degree. u = (8, 4), v = (9, -9)
Usimov [2.4K]

Answer:

<em>71.6 degrees </em>

Step-by-step explanation:

The formula for calculating the angle between two vectors is expressed as;

u.v = |u||v|cos theta

u.v = (8, 4).(9, -9)

u.v = 8(9)+4(-9)

u.v = 72-36

u.v = 36

|u| = √8²+4²

|u| = √64+16

|u| = √80

|v| = √9²+(-9)²

|v| = √81+81

|v| = √162

36 = √80*√162 cos theta

36 = √12960 cos theta

36 = 113.84 cos theta

cos theta = 36/113.84

cos theta = 36/113.84

cos theta = 0.3162

theta = arccos (0.3162)

<em>theta = 71.6 degrees </em>

<em>Hence the angle between the given vectors is 71.6 degrees </em>
