Answer:

= \frac{ 3y}{2}   - 5 \\

we know that,

( - ) \times ( - ) = ( + ) \\ ( - ) \times ( + ) =  ( - )

Let's solve now,

-  \frac{1}{2} ( - 3y + 10) \\  \frac{3y}{2}  -  \frac{10}{2} \\   = \frac{ 3y}{2}   - 5

If (x/100-1)(x/100+1)=kx^2-1 k=
Artist 52 [7]
(x/100-1)(x/100+1)=kx^2-1
(x/100-1)(x/100+1)=(x/100)^2 - 1^2 because it's a difference of squares ( (a-b)(a+b) = a^2-ab+ab-b^2 = a^2 - b^2):
(x/100)^2 - 1^2=kx^2 - 1
(x/100)^2 - 1=kx^2 - 1
(x/100)^2=kx^2
(x^2)/(100^2)=kx^2
1/(100^2)=k
1/10000=k
k=0.0001
