If x and y satisfy both 9x+2y=8 and 7x+2y=4, then y=?
1 answer:
Answer:
The value of y is -5
Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
If x and y satisfy both equations, then (x,y) is the solution of the system of equations
Using a graphing tool
Remember that
The solution of the systems of equations is the intersection point both graphs
The intersection point is (2,-5)
therefore
The solution of the system of equations is the point (2,-5)
The value of y is -5

Answer:
A
Step-by-step explanation:
Consider the parent function The graph of this function is represented as red graph in attached diagram.
Now consider the function
Remind main translations of the graph of the function
- translation a units to the right;
- translation a units to the left;
- translation a units up;
- translation a units down.
In your case, the graph of the function is translated graph of the function
2 units to the left (blue graph). So, correct answer is option A.
