Inversely proportional representation
The mid point is 15 because it is in the middle of 10 and 20
Answer:
1). Option (3)
2). Option (D)
Step-by-step explanation:
1). Integers are the numbers which are whole numbers with negative or positive notations.
Integers can't be a fraction or a number with decimal.
Out of the numbers given,
-18 and 4 will be the integers
Option (3) is the correct answer.
2). Shaded portion of the diagram represents the rational numbers excluding integers,
By the definition of the rational numbers, any number which can be written as a fraction is a rational number.
Rational numbers → All numbers given are the rational numbers
Integers → 
Therefore, only one number
will lie in the shaded region.
Option (D) will be the answer.
Answer:
A) Any value of x makes the equation true. All real numbers Interval Notation: (−∞,∞)
B) Isolate the variable by dividing each side by factors that don't contain the variable. x = 22
C) Any value of x makes the equation true. All real numbers Interval Notation: ( −∞,∞)
A and C are identities and have infinite solutions, while B is neither, and has one solution.
