Remember, think of what they would be like on a number line. The negative number closest to zero is greater than the negative numbers farther from zero. Any number that is to the left of a certain number is less than, if that makes any sense.
<h2>
Therefore x=2 and y= 1</h2>
Step-by-step explanation:
Given equations are
and
.........(2)
⇒
.......(1)
Equation (2)× 3 - Equation (1)

⇔
⇔-10y = -10
⇔y=1
Putting the value of y in equation (1) we get

⇔x =2
Therefore x=2 and y= 1
Answer:
B. 18
Step-by-step explanation:
For the function

we can find the value of the function for all x that are very close to 9 but are less than 9 and for all values of x that are very close to 9 but are greater than 9.
1. For 

2. For 

So, limit exists and is equal to 18.
The <em><u>correct answer</u></em> is:
c)75.4 to 94.6
Explanation:
The formula for a confidence interval is:
,
where μ is the mean, z is the z-score associated with the level of confidence we want, σ is the standard deviation, and n is the sample size.
Our mean is 85, our standard deviation is 12, our sample size is 6, and since we want 95% confidence, our z-score is 1.96:
