Answer:
Given mathematical expression means that '9 is a member of the set T'.
Step-by-step explanation:
We are given the mathematical expression,
' 9 € T '.
In words, it means '9 belongs to T'.
That is, 'the element 9 belongs to the set T' i.e. '9 is a member of the set T'.
Hence, the given mathematical expression means that '9 is a member of the set T'.

Answer:
x = 10 or x = 2
Step-by-step explanation:
Solve for x:
x^2 - 12 x + 20 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 20 from both sides:
x^2 - 12 x = -20
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 36 to both sides:
x^2 - 12 x + 36 = 16
Hint: | Factor the left hand side.
Write the left hand side as a square:
(x - 6)^2 = 16
Hint: | Eliminate the exponent on the left hand side.
Take the square root of both sides:
x - 6 = 4 or x - 6 = -4
Hint: | Look at the first equation: Solve for x.
Add 6 to both sides:
x = 10 or x - 6 = -4
Hint: | Look at the second equation: Solve for x.
Add 6 to both sides:
Answer: x = 10 or x = 2
Answer:
The arrangement of the given equation in the slope - intercept form are

Step-by-step explanation:
Given:
x + y = 4 and
y - 2x = -5
Slope - intercept form :

Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
So, the Slope -intercept form of
x + y = 4 is 
and
y - 2x = -5 is
