Answer:
≈
Step-by-step explanation:
You need to find the value of the variable "x".
To solve for "x" you need to apply the following property of logarithms:

Apply logarithm on both sides of the equation:

Now, applying the property mentioned before, you can rewrite the equation in this form:

Finally, you can apply the Division property of equality, which states that:

Therefore, you need to divide both sides of the equation by
. Finally, you get:

≈
Answer:
Output = 8- input
Step-by-step explanation:
The first point is (1,7)
The input is 1 and the output is 7
The lines goes down, so we know that this is subtraction
Output = 8- input
7 = 8-1
Lets check another point
(5,3)
3 = 8-5
This checks

Answer:
Their mass at the start was 400 kg.
Step-by-step explanation:
Given:
The tyres on a car during a grand prix race are reduced in mass by 3%. Their mass is 388 kg at the end of the race.
Now, to find the mass at the start.
<u>Let the mass at the start be
.</u>
According to question:

⇒
⇒
⇒
<em>Dividing both sides by 0.97 we get:</em>
⇒
Therefore, their mass at the start was 400 kg.
