Get n by itself in both inequalities
(This program doesn't allow for regular less than or greater than signs, so for the purposes of this problem I will be using less than or equal to (≤) and greater than or equal to (≥) signs)
Inequality 1:
![n-4 \geq 5 \\ n \geq 9](https://tex.z-dn.net/?f=n-4%20%20%20%5Cgeq%205%20%5C%5C%20n%20%5Cgeq%209)
Inequality 2:
![2 \geq n+3 \\ -1 \geq n](https://tex.z-dn.net/?f=2%20%5Cgeq%20n%2B3%20%5C%5C%20-1%20%5Cgeq%20n)
Now that you have both of the n's by themselves, you can put the two inequalities together, like this
![-1 \geq n \geq 9](https://tex.z-dn.net/?f=%20-1%20%5Cgeq%20n%20%5Cgeq%209)
Just keep in mind that these are supposed to be regular less than signs
M<K and m<M should be the same size, and m<L and m<N should also be the same size as each other. I would go with C.
Answer:
The solution of the inequality is a < 0.2870
Step-by-step explanation:
* Lets talk about the exponential function
- the exponential function is f(x) = ab^x , where b is a constant and x
is a variable
- To solve this equation use ㏒ or ㏑
- The important rule ㏒(a^n) = n ㏒(a) OR ㏑(a^n) = n ㏑(a)
* Lets solve the problem
∵ 13^4a < 19
- To solve this inequality insert ㏑ in both sides of inequality
∴ ㏑(13^4a) < ㏑(19)
∵ ㏑(a^n) = n ㏑(a)
∴ 4a ㏑(13) < ㏑(19)
- Divide both sides by ㏑(13)
∴ 4a < ㏑(19)/㏑(13)
- To find the value of a divide both sides by 4
∴ a < [㏑(19)/㏑(13)] ÷ 4
∴ a < 0.2870
* The solution of the inequality is a < 0.2870
