Answer:
x = 68
Explanation:
⇒ log₈(x - 4) = 2
<u>apply log rules</u>: logₐN = x then N = aˣ
⇒ (x - 4) = 8²
<u><em>simplify</em></u>
⇒ x - 4 = 64
<u><em>add 4 on both sides</em></u>
⇒ x = 64 + 4
<u><em>add the integers</em></u>
⇒ x = 68
Answer:
B.
Step-by-step explanation:
Every answer besides B. has an input that repeats. A function contains inputs that have exactly one output. This means x values cannot have more than one y value.
Answer:
Option A - ![(+328.62)-(+98.6)=230.02](https://tex.z-dn.net/?f=%28%2B328.62%29-%28%2B98.6%29%3D230.02)
Step-by-step explanation:
We have given the expression ![(+328.62)-(+98.6)](https://tex.z-dn.net/?f=%28%2B328.62%29-%28%2B98.6%29)
We have to find the value of the expression ?
Solution :
Step 1 - Write the expression
![=(+328.62)-(+98.6)](https://tex.z-dn.net/?f=%3D%28%2B328.62%29-%28%2B98.6%29)
Step 2 - Applying symbol rule i.e. multiplication of positive into negative is always negative, ![(-)(+)=(-)](https://tex.z-dn.net/?f=%28-%29%28%2B%29%3D%28-%29)
![=328.62-98.6](https://tex.z-dn.net/?f=%3D328.62-98.6)
Step 3 - Solve
![=230.02](https://tex.z-dn.net/?f=%3D230.02)
Therefore, The value of the expression is ![(+328.62)-(+98.6)=230.02](https://tex.z-dn.net/?f=%28%2B328.62%29-%28%2B98.6%29%3D230.02)
So, Option A is correct.
