The circumference of a circle can be described as the linear distance round the circle
The circumference of a circle = 2πr or πD
π = 3.14
r = radius
d = diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
π = circumference / 2r or circumference / D

For what value of a the system of linear equations Ax 3y a 3?
The system of linear equations has no solution for any value of a.
The equations Ax + 3y = a and 3x + 3y = a can be written in matrix form as
[A 3] [x] [a]
[3 3] * [y] = [a]
By using the Gaussian elimination method, the reduced form of the matrix is
[A 3] [x] [a]
[0 0] * [y] = [0]
This implies that the system has no solution for any value of a.
The system of linear equation
Ax + 3y = a and 3x + 3y = a can be written in matrix form as

Is the function f/x )= x x − 4 − − − − √ is continuous on the interval 4 [infinity]?
No, the function f(x) = x - √x - 4 is not continuous on the interval [4, infinity].
Here's why, A function is considered continuous if the function is defined at every point in its domain and there are no breaks or jumps in the function's graph. In this case, the function f(x) = x - √x - 4 is defined for all x > 4, However, the function includes a square root of x-4, which is defined only for non-negative real numbers, thus for x < 4, the function is undefined. Therefore, the function is not continuous on the interval [4, infinity].

The equation that will make a system with infinite solutions is the third option.
y = 2x + 6
Which equation will make a system with infinite solutions?
A system of linear equations will have infinite solutions only if the two equations represent the same line.
Here we know that one of the linear equations of the system is:
2y - 4x = 12
If we now divide the whole equation by 2, we will get:
(2y - 4x)/2 = 12/2
y - 2x = 6
Now we can move the "2x" term to the right side, then we will get.
y = 2x + 6
So the equations:
y = 2x + 6
2y - 4x = 12
Represent the same line, then that system will have infinite solutions.
Finally, the correct option is the third one.
