Answer: 27.9 let me know if you need a another answer I hope this helps!
She made the mistake in step 4
She should have divided by -2 not just 2 alone
Step-by-step explanation:
Since we have given that
By using logarithmic on both sides we get,
(∵ )
Now, differentiating on both sides ,we get,
Answer:
x = - 6
Step-by-step explanation:
Given
x + 5 = 1 ( subtract 5 from both sides )
x = - 4
Multiply both sides by 3 to clear the fraction
2x = - 12 ( divide both sides by 2 )
x = - 6
Yes because it is linear, also if you set up the proportion 2/4=1/2 they are equal.
