Answer:
Explanation:
This is the given system of equations:
A linear combination of the system is any equation formed by the algebraic addition of both equations, one or both multiplied by an arbitrary constant.
To prove that the given system has no solution you could multiply the first equation times 6 (to get rid of the fractions), multiply the second equation times - 1, and add the two results:
<u>1. First equation times 6:</u>
<u />
<u>2. Second equation times - 1:</u>
<u />
<u>3. Add the two new equations:</u>
<u />
<u>4. Conclusion:</u>
Since 0 = 78 is false, no matter what the value of x and y are, the conclusion is that the system of equations has not solution.
The only choice that represents that same situation is the second one, 0 = 26. That is a possible linear combination that represents that the system of equations has no solutions.
In fact, you might calculate the exact factors by which you had to multiply each one of the original equations to get 0 = 26, but it is not necessary to tell that that option represents a possible linear combination for the given system of equations.
Answer:
-2/3 or 2/-3 ( either one is correct)
Step-by-step explanation:
1. Pick one the points to start with
2. Move either three to the left (if you are starting with x) or move down twice (if you are starting with y)
3. Move up twice (if starting with x) or move three to the right (if starting with y)
4. write the answer with the y at the top and x on the bottom
Answer:
See below
Step-by-step explanation:
I see the term 2x being repeated 5 times, and repeated addition is multiplication, so we can do 5(2x) to get 10x, and we can set that equal to 11 to get 10x=11. Dividing both sides by 10 gets us x=11/10 or x=1.1
-2, 0, 2, and 4 are the x values. To find y, we must substitute x for each of these values in y = -3/2x + 2.
-3/2 times -2 = 3. 3 + 2 = 5. The y value that goes with -2 in the table is 5.
-3/2 times 0 = 0. 0 + 2 = 2. The y value that goes with 0 is 2.
-3/2 times 2 = -3. -3 + 2 = -1. The y value that goes with 2 is -1.
-3/2 times 4 = -6. -6 + 2 = -4. The y value that goes with 4 is -4.
So, the table/coordinates are:
(-2, 5)
(0, 2)
(2, -1)
(4, -4)
I hope this makes the process clear.
