Answer:
Step-by-step explanation:
A 3rd degree polynomial can have a maximum of 3 real roots, but it must have at least 1 real root I believe.
Your answer will be H 170
<span>Subtract 7 from both sides of the equation. Check: Substitute -4 for x in the original equation. If, after the substitution, the left side equals the right side, your answer is correct. ( -4 ) + 7 = 3 </span>
Think of it as a subtraction problem.
-3x -4y = -1
3x - y = -4
_________
0x -5y = -5
y = -5/-5 = 1
Plug 1 in for y in either of the equations
3x -1 = -4
3x = -3
x = -1
Answer: (-1, 1)
