Hello there!
According to the chart, you can see that for every lawn Nina mows, she earns $15. So it's increasing by 15 per yard.
Let's see if this will help:
1 yard= $15
6 yards = ???
I don't want to give you the answer right away, since I want you to learn how to do it. :)
I hope my hint helped!!
(If you're really stuck, take 6 times 15)!
Hope this helped!!

Answer:
The proof contains a simple direct proof, wrapped inside the unnecessary logical packaging of a proof by contradiction framework.
Step-by-step explanation:
The proof is rigourous and well written, so we discard the second answer.
This is not a fake proof by contradiction: it does not have any logical fallacies (circular arguments) or additional assumptions, like, for example, the "proof" of "All the horses are the same color". It is factually correct, but it can be rewritten as a direct proof.
A meaningful proof by contradiction depends strongly on the assumption that the statement to prove is false. In this argument, we only this assumption once, thus it is innecessary. Other proofs by contradiction, like the proof of "The square root of 2 is irrational" or Euclid's proof of the infinitude of primes, develop a longer argument based on the new assumption, but this proof doesn't.
To rewrite this without the superfluous framework, erase the parts "Suppose that the statement is false" and "The fact that the statement is true contradicts the assumption that the statement is false. Thus, the assumption that the statement was false must have been false. Thus, the statement is true."
Answer:
A) 
Step-by-step explanation:
An equation is a function of
when
is the independent variable, that is:
(1)
Where
is the dependent variable.
According to this,
does not represent a function of
, since the independent variable is a function of
, that is,
. Therefore, the correct answer is A.
Answer:
-5x + 56
Step-by-step explanation:
Use distributive property to refine.
20 - 2x + 36 - 3x
Combine Like Terms
-5x + 56
Hope this helps sorry my writing is messy
