Answer:
(5, -2)
Step-by-step explanation:
In the coordinates (7, -5), 7 is the x-coordinate and -5 is the y-coordinate.
The transformation, (x-2 y+3), states that the x-coordinate, 7, must be subtracted by 2.
When subtracted by two, (7 - 2), the difference is 5.
The transformation, (x-2 y+3), states that the y-coordinate must be increased by 3.
When added by 3, (-5 + 3), the sum is -2.
Therefore, the new coordinates are (5, -2).
Answer:
Step-by-step explanation:
We remove the bracket and rearrange the numbers to add them. Only similar variables can be added together.
Yes but it dose depend on the problem
<h3>Answer:</h3>
none of these has "no solution"
<h3>Explanation:</h3>
A. The solution is (8/3, 3)
B. The second equation is -1/2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
C. The solution is (-4, -2)
D. The solution is (4, -2)
E. The second equation is 2 times the first, so these describe the same line. The system has an <em>infinite number of solutions</em>.
_____
A system of equations will have "no solution" when it describes parallel lines—lines that do not intersect. In standard form, such equations are recognizable by their different constants. For example,
- 3x -4y = -4
- 3x -4y = 20 . . . . . . 20 is different from -4
have different constants, so the equations describe parallel lines.
We could multiply one of these by -2 and the system would still be "inconsistent"—having no solution.
