Answer: It is consistent as the lines are intersecting lines and it has a unique solution
Step-by-step explanation:
Since we have given two systems of equation :

We need to check whether the system of equations is consistent or inconsistent.
As we know the formula for checking the consistency :

In first equation we have

similarly,
In the second equation we have

So, According to question, we have

Hence, it is consistent as the lines are intersecting lines and it has a unique solution.
Answer:
D
Step-by-step explanation:
It must first translate 1 unit to the left because quadrilateral F'G'H'I is one unit away from to y axis. It can then translate across the y-axis.
Answer:
first one, put value of x= -3 and y = 0
second one, pit vale of x=7 and y= -7
Step-by-step explanation:
first one,
-14(-3) -20(0) =42
or, 42-0 = 42
or, 42 = 42
proved
second one,
-14(7) -20(-7) = 42
or, -98 + 140=42
or, 42 = 42
proved
the answer to the question is = (x = 1)
