Classify the number 11-6i

a) real number
b) complex number
c) imaginary number

The number is B) complex number.

Here, let’s first see the type of numbers given in the options:

A) Real number:

The numbers which are used to denote the distance is real numbers. The numbers which come under real numbers is rational numbers and irrational numbers.

For example, -5, 2/3, , and so on.

B) Complex number:

The complex numbers are always written as:

Where ‘a’ and ‘b’ are real numbers and ‘i’ is imaginary number. Complex number is a set of all the numbers.

C) Imaginary number:

The numbers which doesn’t exist is imaginary number.

For example, the square is always positive, we cannot get a negative number as a square. So, the square root of the negative number becomes an imaginary number because that number doesn’t exist.

The imaginary number is denoted with ‘i’ where,

So, the given number is a complex number which has real number ‘11’ and imaginary number ‘6i’.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

the answer is c 150
