Answer:

k = - 3

Step-by-step explanation:

$3k + 2k - 6 = 8k + 3 \\ 5k - 6 = 8k + 3 \\ 5k - 8k = 6 + 3 \\ - 3k = 9 \\ k = \frac{9}{ - 3} \\ \huge \red{ \boxed{ k = - 3}}$

Step-by-step explanation:

3k + 2k - 6 = 8k + 3

8k - 3k - 2k = - 6 - 3

8k - 5k = -9

3k = - 9

k = - 9/ 3

K = - 3

Hope it will help you :)

If y − 3 = 3x, which of the following sets represents possible inputs and outputs of the function, represented as ordered pairs?

alekssr [168]

{(3,0),(6,1),(9,2)} because
when you plug in the values you get
3-3=3(0) = 0=0

6-3=3(1) = 3=3

9-3=3(2) = 6=6

Answer:

Step-by-step explanation:

sqrt(28): sqrt(4*7)

sqrt(4) = 2;

sqrt28)=2*sqrt(7)

sqrt(343): sqrt(7 * 7 * 7) = 7 * sqrt(7)

Note: the rule is if you have 3 equal primes under the root sign, you leave one, you throw one away, and you put one outside the root sign.

2 sqrt(63) = 2 sqrt(3*3*7) The above rule gets modified to throw 1 three away and take the other one outside the root sign.

2sqrt(63) = 2*3 sqrt(7)

Numerator: 2*sqrt(7) + 7sqrt(7) = 9sqrt(7)

9sqrt(7)

======

6 sqrt(7)

3/2

Note without brackets I cannot be certain that I have interpreted this correctly. The division only apply to sqrt(343) / 2 sqrt(63). If this is so please leave a note.
