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.
The seats are increasing at a rate of four per row. If you were to write this in an equation, it would be y=4X+20, with 4 as the rate of change, 20 as the original amount of seats, and Y as the total number of seats for X rows. Plug in 25 for X and you'll get an answer of 120 seats.
Answer:
Step-by-step explanation:
(10 - 1)/(0 - 3) = -9/3 = -3
y - 1 = -3(x -3)
y - 1 = -3x + 9
y = -3x + 10
Answer:
x = 22
Step-by-step explanation:
The expression "six less than twice a number x" can be written as 2x - 6. So:
2x - 6 = 38
2x = 44
x = 22
