F(x) = -x - 3 Find f(-4) f(-4) = -(-4) -3

skelet666 [1.2K]

Answer:

$\boxed{ \bold{ \boxed{ \sf{f( - 4) = 1}}}}$

Step-by-step explanation:

Given, f ( x ) = - x - 3

Let's find the value of f ( - 4 )

$\sf{f( - 4) = - ( - 4) - 3}$

We know that , $( - ) \times ( - ) = ( + )$

⇒ $\sf{ 4 - 3}$

Subtract 3 from 4

⇒ $\sf{1}$

Hope I helped!

Best regards!!

81(p+q)^2-9p-9q Factor this

polet [3.4K]

Answer:

9(p + q)(9p + 9q - 1)

Step-by-step explanation:

Given

81(p + q)² - 9p - 9q ← factor out - 9 from these 2 terms

= 81(p + q)² - 9(p + q) ← factor out 9(p + q) from each term

= 9(p + q)(9(p + q) - 1)

= 9(p + q)(9p + 9q - 1)
