Answer:

1. 3+16-2k=3k-1 (distributive property)

2.  -2k+19=3k-1 (like terms)

3. -2k+20=3k (added 1 on both sides, addition property)

4. 20=5k (added 2k on both sides, also addition property)

5. 4=k (divided 5 on both sides, division property)

So;

k=4

15. 3x – 4y = -1<br> 5x + 2y = 7
never [62]

Answer:

x = 1, y = 1

Step-by-step explanation:

3x - 4y = -1

5x + 2y = 7

If we multiply the whole second equation by 2, we get:

10x + 4y = 14

Adding this to the first equation:

10x + 4y + 3x - 4y = 14 - 1

13x = 13

x = 1

Applying this to the second equation:

5 (1) + 2y = 7

2y = 2

y = 1

Flauer [41]

Answer:

Step-by-step explanRemember: logax=b⇒ab=x

in which "a" is the base of the log. 

log4 (1/16) = 4^-2 = 1/4^2 = 1/16

4 to the power of -2 is equal to 1/16.

To answer this question, the equation in exponential form of "log4 (1/16) = -2" is " 4^-2 " (4 to the power of -2). :D
