<span>Reflection in the line y = x. A reflection in the line y = x can be seen in the picture below in which A is reflected to its image A'. The general rule for a reflection in the y-axis: (A, B) (B, A)</span>
Answer:
If solving for X. (didn't know if you were solving for X or Y.
x=2y-12
x=5y-15
Step-by-step explanation:
x-2y=-12
+2y on both sides
x=2y-12
x-5y=-15
+5y on both sides
x=5y-15
Answer:
Option (c) is correct.
Add a constant to a row does not involves while solving a system of equations using matrix.
Step-by-step explanation:
Given : solving a system of equations.
W have to choose from given options that can not be used on a matrix when solving a system of equations.
Since solving the system using matrix method involve
1) adding of rows,
2) multiplying a row by a constant.
3) interchange rows
But add a constant to a row does not involves while solving a system of equations using matrix.
Thus, Option (c) is correct.
Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
Let larger number be X and smaller one be Y.
The two equations are :-
X = 2Y + 3
X = 2Y + 1
As you can tell, the slopes are the same and the y-intercepts are different. So, they will not intersect. Therefore, no solutions exist for this situation.
Answer:
X+0.375=y
