Answer:

Step-by-step explanation:

Factor the polynomials.

x^2-4 = (x+2)(x-2)

x^2+5x+6 = (x+3)(x+2)

(x^2-4)/(x^2+5x+6) = (x+2)(x-2)/[(x+3)(x+2)] = (x-2)/(x+3)

Y is equal to the additive inverse of 4x. Use this information to find the value of the expression 17x + 3y in terms of x.
nevsk [136]

Answer:

<h3>5x</h3>

Step-by-step explanation:

The additive inverse of a function is that value added that will sum it up to zero

If y is the  additive inverse of 4x, then y = -4x

Given the expression 17x+3y

Substitute y = -4x into the expression to have;

17x + 3(-4x)

17x -12x

5x

Hence the value of the expression in terms of x is 5x

Ksju [112]

Answer:

26,733

Step-by-step explanation:

39,900 - Percentage decrease =

39,900 - (33% × 39,900) =

39,900 - 33% × 39,900 =

(1 - 33%) × 39,900 =

(100% - 33%) × 39,900 =

67% × 39,900 =

67 ÷ 100 × 39,900 =

67 × 39,900 ÷ 100 =

2,673,300 ÷ 100 =

26,733

Hope this helps :)
