The <em><u>correct answer</u></em> is:
non-extraneous
Explanation:
An extraneous solution is one that we arrive at that will not work in the equation. For rational equations such as we have, extraneous solutions are ones that will cause the denominator to be 0. For ours, that would mean x=-5.
The equation we have is:
We will multiply everything by (x+5) in order to get that off the bottom of the fractions:
Multiply all terms by 5 to eliminate the fraction:
Combine like terms:
20+x = 10
Subtract 20 from each side:
20+x-20 = 10-20
x = -10
Since this is not -5, this is not an extraneous solution.
Answer:
7.22
Step-by-step explanation:
11.2 minus 3.98
1/5 is reduced to .2
hope this helps
The rule of law of the square root of constants is taking the nearest divisible number which has a square root of an integer. since 25 taken to the power of 0.5 is equal to 5 or -5, the rule already applies. In this case, 2 multiplied to 5 is equal to choice E. 10.
Answer:
Easy! The cool thing about correlations is you can easily determine them by reading your graph, no hard brain work involved!
It should be A.
Step-by-step explanation:
By looking at the graph, you can already determine that the correlation is negative, since it's going down, not up.
Now, you need to read what is happening on the graph. As the price (X-Axis) is increasing, less people are spending their money, presumably because it's not priced affordably. So as you can see according to your Y-Axis, the amount of people buying is lowered.
Hopefully this isn't confusing!
