Final answer:
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.
