12) Add the fractions, and simplify if possible.<br><br> (y+7)/(y^2-y-12) - 2/(y^2-9)
lianna [129]

Answer:

\dfrac{y^2+2y-13}{(y-4)(y+3)(y-3)}

Step-by-step explanation:

Given the expression

\dfrac{y+7}{y^2-y-12}-\dfrac{2}{y^2-9}

First, factor each denominator:

1. y^2-y-12=y^2-4y+3y-12=y(y-4)+3(y-4)=(y-4)(y+3)

2. y^2-9=(y-3)(y+3)

Now the expression is

\dfrac{y+7}{(y-4)(y+3)}-\dfrac{2}{(y-3)(y+3)}

Now, multiply the first numerator by (y-3) and the second by (y-4) and write the result as a fraction with denominator (y-4)(y+3)(y-3):

\dfrac{(y+7)(y-3)-2(y-4)}{(y-4)(y+3)(y-3)}=\dfrac{y^2-3y+7y-21-2y+8}{(y-4)(y+3)(y-3)}=\dfrac{y^2+2y-13}{(y-4)(y+3)(y-3)}

This fraction cannot be simplified more.

1/2 ÷ 2 = 1/4 because A)1/4 × 2 = 1 /2 B) 1 /8 × 4 = 1 /4 C) 1 /16 × 8 = 1 /2 D) 1 /32 × 16 = 1/ 2
EleoNora [17]

Answer:

A)

Step-by-step explanation:

(1/2)/2 = 1/4 because

(1/2)/2 = (1/2) * (1/2) = (1 * 1)/(2 * 2) = 1/4

In essence, to solve this equation, you must:

1) Flip the second fraction (or put the whole number under 1).

2) Change the divide sign into the multiply sign.

3) Multiply across.

A) 1/4 x 2 = 1/2 is your answer choice, for it is the opposite of the question.
