Which equation is an identity?

3w + 8 – w = 4w – 2(w – 4)

–3y + 3 = –3y – 6

9 – (2v + 3) = –2v – 6

7m – 5 = 8m + 7 – m

The identity is 3w + 8 – w = 4w – 2(w – 4)

2w+8=4w−2(w−4)

2w+8=4w−2w+8

2w+8=2w+8

Since both sides equal so it is an identity

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  .
