B. Closed circles tell u that it’s less than or equal to/greater than or equal to and it stops at -3 and 5
No - there is a rule that state that the sum of two sides of a triangle must be greater than the 3rd side.
While 9+15 >4
and 4+15 >9
9+4 is not greater than 15 - so this triangle cannot be made.
Some numbers cannot be written as a ratio of two integers they are called irrational numbers.
Example: Pi is a famous irrational number. You cannot write down a simple fraction that equals Pi.
A decimal goes on forever without repeating.
Here's the derivation.
(f x g)(4) = f(4) x g(4)
So applying the derived equation.
(f x g)(4) = 3(4) - 7 * -2(4) - 6
(f x g)(4) = 5 * -2
(f x g)(4) = -10
