By solving the inequality we get y\leq -3

What is graphing the inequality?

The act of illustrating which area of the number line contains values that will "satisfy" the specified inequality is known as graphing the inequality. Take a look at the first inequality, "x > -5." The numbers that can be used to substitute x in our inequality to produce a true statement can be shown on a graph of our inequality.

3y\leq -9

Dividing above equation by 3 we get,

\frac{3y}{3}\leq \frac{-9}{3}\\y\leq -3

Graph of y\leq -3 is

Therefore by solving the inequality we get y\leq -3

Hey could anyone explain how to answer this kind of question? Or just solve and show what you did! Thank you!
STALIN [3.7K]

Step-by-step explanation:

  • 9x-3=60°{each angle of equilateral triangle is 60°}
  • 9x=60+3
  • x=63/9
  • x=7

so,

  • 9x-3
  • 9×7-3
  • 63-3
  • 60°

hope it helps.

Factor 9y2 - 12y + 4.<br><br> (3 y - 2)(3 y + 2)<br> (3 y - 4)( y + 1)<br> (3 y - 2) 2
lozanna [386]

Answer:

(y - 2)²

Step-by-step explanation:

9y² - 12y + 4 ← is a perfect square of the form

(ax - b)² = a²x² - 2abx + b²

Compare like terms with 9y² - 12y + 4, thus

a² = 9 ⇒ a = 3

b² = 4 ⇒ b = 2 and

- 2ab = - 2 × 3 × 2 = - 12

Thus

9y² - 12y + 4 = (3y - 2)²

tatuchka [14]
9x² - 49

(3x)² - (7)²

= (3x + 7)(3x - 7)

This type of factoring is called Difference of Two Squares
