Write a situation in which positive and negative numbers are ised to describe values that have opposite meaning. What does 0 represent in this situation you created?

(08.01)consider the following pair of equations: x + y = −2 y = 2x + 10 if the two equations are graphed, at what point do the lines representing the two equations intersect? (−4, 2) (4, 2) (−2, 4) (2, 4)

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

If x = -2, then x 2-7x+10 equals a. 0 b.20 c.28
