Answer:

imagine the upper triangle as the same as the lower one, but rotated by 180° around the corner point they share, and resized.

the base of the smaller triangle is resized by a factor of 3/4.5, or reduced: 1/1.5

we just take the length from the hypotenuse of the bigger triangle and resize it to, either by multiplying with 1/1.5 or by dividing by 1.5

personally, I find the latter easier.

x = 7.5/1.5 = 5

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!
