Well, with the equation in that form, it may not be obvious how to graph it.
So let's change just the form a little bit... without changing the equation:
<u> y - 5 = 0</u>
Add 5 to each side: <em>y = 5 </em>
Look at that for awhile, and think about what it tells us.
It says that 'y' doesn't depend on 'x' at all. No matter how far left or right
you go on the graph, the y-value of <em>every point</em> is 5 .
The graph is a horizontal line across the graph. It cuts across the y-axis at
the point where y=5 , and it stays exactly at that same height everywhere.
Answer:
1) k = 3
2) 3, 4, 5
3) k + (k + 2) + (k + 4) = 4k
4) 6, 8, 10
Step-by-step explanation:
Jared used the equation;
k + (k + 1) + (k + 2) = 4k
Let's find k.
3k + 3 = 4k
4k - 3k = 3
k = 3
Thus,the integers will be;
3, (3 + 1) and (3 + 2)
This is; 3, 4, 5
He is looking for consecutive even integers but yet got 3 and 5 which are odd numbers. However, he should have used the format;
k, (k + 2), (k + 4) as the 3 consecutive even integers.
Thus, rewriting the main equation gives;
k + k + 2 + k + 4 = 4k
3k + 6 = 4k
4k - 3k = 6
k = 6
Thus,the integers are;
6, (6 + 2), (6 + 4)
This is; 6, 8, 10
For this case we have the following system of equations:
We can write a system of equivalent equations.
For this, it is enough to multiply one of the two equations by a scalar.
Multiplying the equation 1 by 2, we have:
Therefore, the new system of equations is:
