Answer:
<h2>GRAPH III</h2>Step-by-step explanation:
Look at the picture.
We have
y = x² - 4 → move the graph of x² 4 units down (the vertex is (0, -4))
x + y + 2 = 0 <em>subtracy x and 2 from both sides</em>
y = -x - 2 → move the graph of -x 2 units down (the y-intercept os -2)
Only graph III and IV meets these conditions.
The solution is the points of intersection of the graphs.
Therefore your answer is GRAPH III

The value of "a" is 4
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
The above expression involves variables and constants
A variable is a symbol that represents an unknown number
Here the variable is "a"
Constants are fixed numbers like 1, 2 etc
<em><u>From given expression:</u></em>
Move the varibale "2a" from right side to left side of equation
When, 2a is moved from R.H.S to L.H.S, it becomes -2a
Now move the constant -2 from left side to right side of equation
Similarly, when -2 is moved from L.H.S to R.H.S, it becomes +2
Now add the variables on left side of equation
Now add the constants on right side of equation
Cancel the negative sign on both sides of equation
Thus the value of "a" is 4
