For this case we must solve the following equation:

For this, we follow the steps below:
We find the Neperian logarithm on both sides of the equation to remove the variable from the exponent

We use one of the logarithm properties to extract x from the exponent:

We subtract xln (7) on both sides of the equation:

We take x common factor:

We divide between
on both sides of the equation, then:

Answer:

Answer:
k = -23
Step-by-step explanation:
-14=k+9
Subtract 9 from each side
-14-9 = k+9-9
-23 = k
1. A rational number is a number that can be written as a fraction.
For example: 1/3, 5/7, 90/666, etc
Note: Any integer can be written as a fraction.
Look:
5 = 5/1 = rational
-14 = -14/1 = rational
2. There is no difference between a rational and integer.
Mean a=75/10, mean b=73/10............about the same
range a=2-10=8, range b=4-12=8.........about the same
