First you have 30 cds and 5 if them are country.

You have 5/30 chance to take one country = 0.1666...= 16,6%

Next time you gonna pick up one you have 29 cds and 4 country

4/29= 0,1379=13,8%

Which function has the same y-intercept as the function?<br>

rosijanka [135]

Answer:

$6x -7y = 21$

Step-by-step explanation:

The $y$ -intercept of a line is the $y$ value when $x = 0$ . In the equation $y = \frac23 x -3 \\$ , we can solve for its equation when we plug in $x = 0$ .

Solving for $y$ when $x = 0$ :

$y = \frac23 x -3 \\ y = \frac23 (0) -3 \\ y = -3$ .

So the $y$ -intercept of the equation $y = \frac23 x -3 \\$ is $-3$ .

To find what equation has the same $y$ -intercept, we can do the same process for each equations given by the choices. However, I can see that the equation, $6x -7y = 21$ , has the $y$ -intercept. If in doubt, you can check for the solution below or solve each equations for yourself.

Solving for $y$ when $x = 0$ :

$6x -7y = 21 \\ 6(0) -7y = 21 \\ 0 -7y = 21 \\ -7y = 21 \\ \frac{-7y}{-7} = \frac{21}{-7} \\ y = -3$
