Answer:

y=-6 and x=0

Step-by-step explanation:

-4x -2y = -12

4x + 8y = -24

(add the equations)

6y = -36

-36/6 = -6

y=-6

(Add y value in any of the equations)

-4x-2(6) = -12

-4x-12=-12

-4x=0

x=0

For f(x)=1/x^2-3
igomit [66]

For f(x)=1/x^2-3

Find  

A) f(3)

B) f(2-h)

If f(x)=1/x^2-3, then f(3) = 1 / 3^2 - 3.  The exponentiation here must be carried out first:  f(3) = 1/9 - 3.  Then f(3) = 1/9 - 27/9 = -26/9

If f(x)=1/x^2-3, then f(2-h) = 1 / [2-h]^2 - 3.  This result may be left as is or expanded.  In expanded form, we have:

                     1

f(2-h) = ------------------ - 3

              4-4h +h^2
