You answer would be B. Vehicle B needs fewer repairs then Vehicle A on average and its repair rate is more consistant
Solution:
<u>A few definitions...</u>
- Rational number - Any integer, fraction, terminating decimal, or repeating decimal is classified as a rational number
- Irrational number - All the real numbers which are not rational numbers.
<u>Option A - Rational or Irrational?</u>
Since both are known as fractions, they are rational numbers.
<u>Option B - Rational or Irrational?</u>
√2 is classified as an Irrational number because if it is simplified, it does not result in any integer, fraction, terminating decimal, or repeating decimal.
<u>Option C - Rational or Irrational?</u>
- 1/√4 + 7/2
- => 1/2 + 7/2
- => 8/2 = 4
Since this is an integer, this is rational.
<u>Option D - Rational or Irrational?</u>
- √9 + √4
- => √3 x 3 + √2 x 2
- => 3 + 2 = 5
Since this is an integer, this is rational.
In conclusion...
Option B is correct.
Answer:-4x+3y=1
Step-by-step explanation:
First put the equations above one another
-2x+7y=-5
-2x-4y= 6
Just add the corresponding number from the top from the one right below it
-2x plus -2x is 4x
7y plus -4y is 3y
-5 plus 6
Then bring down the equal sign
And you get
-4x+3y=1
