Answer:(x - 1)(7x + 12)
Step-by-step explanation:
Question: (6x² + 5x - 3) + (x² - 9)
⇒(6x² + 5x - 3) + (x² - 9)
⇒6x² + 5x - 3 + x² - 9
rearrange
⇒6x² + x² + 5x - 3 - 9
⇒7x² + 5x - 12
Middle term break
⇒7x² + 12x - 7x - 12
⇒x(7x + 12) - 1(7x + 12)
⇒(x - 1)(7x + 12) Answer

Answer:
Step-by-step explanation:
- 2x > 17
x < 17 ÷ ( - 2 )
x < - 8.5
x ∈ ( - ∞ , - 8.5 )
The greatest integer that satisfies the inequality is ( - 9 )
A linear regression equation is a line so it has a form of y = mx + b, which is an equation of a line. You will also see it as Y = a + bX. In the form of Y= a +bX the b is the slope.
There are different methods to fitting a line and the most common method is the method of least-squares.
