Can anybody help me with number 20....just number 20 plz?....thank u

MatroZZZ [7]

The property used in #20 was called 'the distributive property'.

This property gets rid of the parenthesis and also gets the expression more simple.

x(y+b)
x*y + x*b ⇔ Notice the change here?

Answer would be: Distributive property

For the functions f(x)=−7x^2−x and g(x)=9x^2−4x, find (f−g)(x) and (f−g)(1)

musickatia [10]

Answer:

See below.

Step-by-step explanation:

$f(x)=-7x^2-x\\g(x)=9x^2-4x\\(f-g)(x)=f(x)-g(x)\\(f-g)(x)=(-7x^2-x)-(9x^2-4x)\\(f-g)(x)=-7x^2-x-9x^2+4x\\(f-g)(x)=-16x^2+3x\\\\(f-g)(1)=-16(1)^2+3(1)\\(f-g)(1)=-16+3=-13$
