4/y+2 - 9/y-2 = 9/y^2-4

Evgesh-ka [11]2 years ago

Going off the idea that this is 4/(y+2) - 9/(y-2) = 9/(y^2-4), let's first rewrite y^2-4 in the form of a^2-b^2, where a=y and b=2.
y/(y+2)-9/(y-2)=9/(y^2-2^2)
Now, use difference of squares: a^2-b^2=(a+b)(a-b)
4/(y+2)-9/(y-2)=9/((y+2)(y-2))
Multiply both sides by the Least Common Denominator: (y+2)(y-2)
4(y-2)-9(y+2)=9
Then keep on simplifying until you get your answer
-5y-26=9
-5y=9+26
-5y=35
y=35/-5
y=-7
Yay! Our answer is y=-7!

If the coordinates of A and B are (-3, a) and (1, a+4) respectively and the mid point of AB is (-1, 1),
goldfiish [28.3K]

a=-1

Using the midpoint formula directly from the topic meaning

\frac{x_{1}+x_{2}  }{2}  or  \frac{y_{1}+y_{2}  }{2}

so

\frac{a+a+4}{2} =1\\a=-1

iren2701 [21]

Answer:

x = 94.25 kg

Step-by-step explanation:


We can set up ratios to determine the number of kg.


4 bushels    6.5 bushels

-------- --    = --------------

58 kg              x kg


Using cross products

4 * x  = 58 * 6.5

4x = 377

Divide by 4

x = 94.25 kg
