Evaluate m^0 - n^2 for m = 2 and n = -1.

A. -1
B. 0
C. 1

B) 0

Step-by-step explanation:

When the exponent is 0, it will always equal 1.

For example:

Since you know the values of m and n, substitute/plug it into the equation:

  Plug in 2 into "m" since m = 2, and plug in -1 into "n" since n = -1

1 - (1)

0           Your answer is B

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
