<h2>Explanation:</h2>
Hello! Remember you have to write complete questions in order to get good and exact answers. Here you have provided neither the graph nor the equation, so I could help you providing my own graph and equation. From physics, we know that speed, time and distance are related in the following form:
So is the slope of a line that passes through the origin where
matches the y-axis and
matches the x-axis. So we can write:
From the graph, we can know that:
And the equation that I provide is:
If both speeds are given in mi/h, then by comparing them, we can say that <em>the speed (rate) of the first car (graph) is 20mi/h less than the speed of the second car (equation)</em>
Given:
The equation is
To find:
The error and correct solution.
Solution:
We have,
Add 16 on both sides.
Divide both sides by -5.
Third step is incorrect because he divide the equation by 5 instead of -5.
Therefore, the correct solution is .
Answer:
17576000 different License plates are possible.
Step-by-step explanation:
Here we will use repetitive permutations.
First 3 digits of the license plates have letters from a to z and next 3 digits have numbers from 0 to 9.
Now, 26 letters ( a to z ) can take 3 positions with repetition in ways.
And 10 numbers ( 0 to 9 ) can take 3 positions with repetition in ways.
So the total number of license plates that can be made =
= 17576
1000 = 17576000 plates.
