63/3= 21
So 21 miles per gallon of gas
To find 7, you multiply it by 7
21*7= 147
147 miles on 7 gallons of gas
5000000/10=50000 ........
Answer:
broo even i have math exams tomorrow but i am in 6th grade
Step-by-step explanation:
You could check these four answers by subbing them, one by one, into the original equation. Or you could immediately apply the quadratic formula to
<span>x^2 -6x-22. I'd rather be proactive and calculate the roots myself.
Using a=1, b= -6 and c = -22, we get discriminant (-6)^2 - 4(1)(-22), which evaluates to 36+88 = 124. 124 in turn can be factored: 124 = 4(31).
then:
-(-6) plus or minus sqrt( [-6]^2 - 4(1)(-22) )
x = ----------------------------------------------------------
2
6 plus or minus 2*sqrt(31)
= -----------------------------------------
2
= 3 plus or minus sqrt(31)
Note that these are REAL roots, in complete disagreement with the four answer choices. Please ensure that you have copied the quadratic expression accurately.
Remind yourself that if the discriminant is +, as it is in this case, you have 2 distinct real roots.</span>
Answer:
- <u><em>No, if the left-hand limit fo a function approaches infinity because there is a vertical aymptote the limit does not exist.</em></u>
<u><em /></u>
Explanation:
<h2>Important: infinity is not a value!</h2>
When it is said that a limit approaches infinity, it means that the function becomes indefinitely large: as you get closer and closer to the input value, the function becomes larger and larger; in this case, no value can be assigned to the limit, that is, <em>the limit does not exist</em>
For there to be a limit, the function has to approach a specific value. Infinity is not a number; it does not indicate a particular value; again, the limit does not exist.
