Okay, here we have this:
Considering the provided function, we are going to calculate the requested one-side limits, so we obtain the following:
Answer:

And we can use the following formula:

And replacing the info we got:

Step-by-step explanation:
We define two events for this case A and B. And we know the probability for each individual event given by the problem:


And we want to find the probability that A and B both occurs if A and B are independent events, who menas the following conditions:


And for this special case we want to find this probability:

And we can use the following formula:

And replacing the info we got:

<span>I believe your answer will be 10 & 20, because they BOTH are multiples of 40, ANNNNNNNNNNNNNNNNND when added together they equal 30! =D
I hope I helped! =D</span>
The correct answer is D? Its the only one that makes sense.
Answer:
D) the lines coincide
Step-by-step explanation:
1. y = 4 - x
2. 2y = 8 - 2x
divide eq2 by 2:
y = 4 - x
eq 1 and 2 are identical
