3 0

Answer:

Yes, because the linear function  x - y = 5 is a function

Step-by-step explanation:

x - y = 5  can look like   y = x - 5  with slope 1 and y-intercept -5

so this is a function  which makes set K a function.

5 green marbles 5 red marbles 10 yellow marbles
Andrews [41]

Answer:

5/19

Step-by-step explanation:

Marbles=20

So the probability of choosing not yellow is 10/20=1/2.  

Marbles are not replaced.

The total number is 19

The probability of choosing yellow is 10/19

So the final answer is (1/2)*(10/19)=5/19.

hope this helps

Solve the equation for y <br><br> 5 ( y + 1 ) = 30 <br><br> y = ??
nexus9112 [7]
Hi again :)

5(y + 1) = 30
Once again, use the distributive property
(5)(y) + (5)(1) = 30
5y + 5 = 30
Add -5 to both sides
5y + 5 - 5 = 30 - 5
5y = 25
Divide both sides by 5
5y/5 = 25/5
y = 5

Best of luck!
