Represent the solution of 3x + 9 ≤ 12 in a number line where x in an integer
Answers
Answer:
That's the required answer hope it's right
Given : 3x + 9 ≤ 12
To Find : represent on number line
Solution:
Numbers with a negative sign are less than zero
Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.
+ sign numbers can be denoted as simply numbers
On a number line the number increases as we move to the right and decreases as we move to the left.
3x + 9 ≤ 12
=> 3x ≤ 12 - 9
=> 3x ≤ 3
=> x ≤ 1
number line will be on left side of 1 , including 1,
dark dot will be at at 1 and a line left side of that will represent x ≤ 1
i.e : 3x + 9 ≤ 12
