Consider this expression to combine the like terms:
4mn + 3m – 6n – 7mn + 2n + 0.5m
4mn – 7mn =
3m + 0.5m =
–6n + 2n =

-3mn + 3.5m - 4n

Step-by-step explanation:

Combine like terms:

4mn + 3m - 6n - 7mn + 2n + 0.5m = 4mn - 7mn + 3m + 0.5m - 6n + 2n

(4mn - 7mn) + (3m + 0.5m) + (-6n + 2n) = -3mn + 3.5m - 4n

-3mn + 3.5m - 4n is your answer.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
