Answer:
8x + 3y = -47
Step-by-step explanation:
1. Use the y = mx + b form to find b:

2. Plug in b for the new equation:

3. Get rid of the denominators and simplify everything into standard form
(ax + by = c)

You just need to divide to get to 1n. -3n = 84
So the answer is 84/ -3 = -28. n= -28
Answer:
A
Step-by-step explanation:
Given
p² - 16 = 0 ( add 16 to both sides )
p² = 16 ( take the square root of both sides )
p = ±
= ± 4
Thus solution is { - 4, 4 } → A
