9. Solve the system of equations using substitution.<br>y = 2x - 10<br>y = 4x - 8

krok68 [10]

Since they’re both in standard form and they both say that y is equal to something, you just have to set them up with one another
2x-10=4x-8
Subtract 2x
-10=2x-8
Add 8
-2=2x
Divide by 2
-1=x
x=-1
Check it by inserting it
2(-1)-10=4(-1)-8
-2-10=-4-8
-12=-12
So x=-1 is the answer

Answer: 0.3679

Step-by-step explanation:

The cumulative distribution function for exponential distribution is :-

$P(x)=1-e^{-\lambda x}$ , where $\lambda$ is the mean of the distribution.

Given : A mean length of waiting time equal $2.8$ minutes

i.e. Mean number of calls answered in a minute $\lambda=\dfrac{1}{2.8}$

Now, the proportion of callers is put on hold longer than 2.8 minutes is given by :_

$P(x>2.8)=1-P(x$

Hence, the proportion of callers is put on hold longer than 2.8 minutes = 0.3679

Please help me out on this question

Mariulka [41]

At x=2, y=4

At x=4, y=16

So the total change in y from x=2 to x=4 is 16-4=12

And since average rate of change = total change in y divided by total change in x within the same period, therefore the answer is 12/2 = 6

Hope that helps. Let me know if you have any questions.
