I suppose that you should have given some pairs to choose from.
Anyway, I can tell you how to do it. Given a pair 
, you have to substitute 
and 
to 
and 
respectively, and see if you get something true.
For example, the pair 
satisfies the function, because the substitution yields
which is true. On the other hand, the pair 
doesn't satisfy the function, because
is clearly false.
Answer:
-2x-24
Step-by-step explanation:
so you need to use pemdas first
-5x+3x-24 and then combine like terms
-2x-24
28/8 = (28÷4)/(8÷4) = 7/2;
m^2 / m^3 = (m^2÷m^2)/(m^3÷m^2) = 1/m;
n^4/n^2 = (n^4÷n^2)/(n^2÷n^2) = n^2;
Finally, we obtain 7n^2/2m ;
Answer:
= 3 -1.202
Step-by-step explanation:
20 000 is as much as 20 * 1 000, so we can write it as: 20 * 10^3
3 400 000 is as much as 34 * 100 000, so we can write it as: 34 * 10^5
The sum in scientific notation would look like this:
20 * 10^3 + 34 * 10^5
I hope that's what you meant :)
