Question

M = 3n^(2)-n-7 when n equals -1

Answer 1

m=3*-1^2-(-1)-7

m=-9-(-1)-7

m=8-7

m=1

Answer 2

The value of m is calculated to be -3 when substituting n = -1 into the equation m = 3n² - n - 7.

Step-by-step explanation:

To solve for m when n equals -1 in the equation m = 3n² - n - 7, we substitute -1 into the equation:

m = 3(-1)² - (-1) - 7

m = 3(1) + 1 - 7

m = 3 + 1 - 7

m = -3

Hence, the value of m is -3 when n equals -1.
