Find k so that the three equations 3x-y=2, 2x+8=3y, and y=kx have a common solution

1 answer:

8 0

2x+8=3kx (3k-2)x+8=0
3x-kx=2. (3-k)x-2=0
3k-2)x+10=3-k)x
4k-5=10/x
///////
3x-y-2=2x+8-3y
X+2y-10=0
X+2kx-10=0
K=(10-x)/2x

Option 2: $\frac{x-12}{4}$ is the correct answer

Step-by-step explanation:

Given fraction is:

$\frac{2x-24}{8}$

In order to simplify, we can see that the function is already in compact form

So,

We can simplify the given fraction.

We can see that the numerator can be further simplified

$\frac{2(x-12)}{8}\\=\frac{x-12}{4}$

Hence,

Option 2: $\frac{x-12}{4}$ is the correct answer

Answer:

There is a 1/8 chance.

If there are 4 cards in the deck, and one three card, it makes it a 1/4 chance of picking the card the first time.

The probability stays the second time you pull out a card.

So, you would do the equation 1/4 * 1/4, which is 1/8. That is the answer.
