The difference of 3 times a number and 15 is no less than the square of the number.
Select the inequality that represents this relationship.
A. 3x – 15 > 22
B. 34 < x2 + 15
c. 3x < 32 – 15
D. 3x + 15 > 22

Respuesta :

Answer:

(B) The inequality that represents this relationship is [tex]3x  < x^2 +15[/tex]

Step-by-step explanation:

Let us assume the given number = x

⇒ 3 times the given number = 3 (x)  = 3x

Square of the given number = [tex](x)^2  = x^2[/tex]

Now, According to the question:

The difference of (3 x) and 15 is no less than [tex] x^2[/tex]

⇒ [tex]3x - 15 < x^2\\ \implies 3x  < x^2 +15[/tex]

or, [tex]3x  < x^2 +15[/tex]

Hence, the given inequality is represented as [tex]3x  < x^2 +15[/tex]

Answer:

3x - 15 > [tex]x^{2}[/tex]

Step-by-step explanation:

Let the number be x

⇒3 times the number is 3x and square of the number is [tex]x^{2}[/tex]

Difference of 3 times a number and 15 is 3x -15

⇒This difference is no less than the square of the number

⇒The difference is greater than or equal to square of the number

3x - 15 ≥ [tex]x^{2}[/tex]
