Try this:
1. sum of numbers is x+y=67, the difference between them is x-y=11
2. it is possible to make up and resolve the system:
\left \{ {{x+y=67} \atop {x-y=11}} \right. \ =\ \textgreater \  \  \left \{ {{x=39} \atop {y=28}} \right.

How can the quotient of powers law be used to show that a negative exponent is equivalent to the reciprocal
Kay [80]

Answer:Thus,  (-3)-4 = 1/(-3)4.

Step-by-step explanation:

Negative exponents have the following property:   n-m = 1/nm   OR   1/n-m = nm

So for  (-3)-4 ,  n= -3 and -m= -4 (or m= 4).

Thus,  (-3)-4 = 1/(-3)4.

Can an answer be incorrect even if it looks reasonable?
Anna [14]

Answer:

  • <em>Yes, an answer can be incorrect even it it looks reasonable.</em>

Explanation:

Yes, an answer can be incorrect even if it looks reasonable, for two main reasons:

  • The assumptions (premises or statements) on which the reasoning is based are wrong.
  • The reasoning sounds good but it is a fallacy.

To avoid the first condition you must be sure about the facts, which may be information from an experiment that you performed or from a source. In order for an answer be correct, make sure your premises are true.

Dealing with the second condition, a fallacy is an argument that seems strictly logical but is misleading: you must learn which reasonings are really valid; this is, that the conclusion unequivocally follows from the premises.

There are rules for the arguments to be valid, and that is the object of logic study.

Fallacies are sometimes used by those interested in supporting a point of view without having true reason on their side. You should have some knowledges about logic to avoid being victim of the fallacies, which can drive you to make wrong decisions.

(06.01)The tables below show four sets of data:
Yakvenalex [24]
For it to be non-linear, the rate of change cannot be constant.  For the first table the rate is a constant 1 and the second table has a constant rate of -1.  The 3rd and 4th tables have no constant rate and thus are non-linear.

The 4th table is increasing while the 3rd table is decreasing.  

So the 3rd table, Set C, is the only non-linear negative association between x and y.
