True, if a points works in both equations of a linear system, then that point is the solution.
Answer:
-2
Step-by-step explanation:
-7 + 5 = -2
If you have negatives and then add, the negative number will decrease.
if the question was -7 - 5, the answer would be -12. This is because when you subtract a number from a negative, the negative number becomes bigger.
This is actually a "product," not an "answer."
Nothing to simplify here. Instead, you are to multiply these two "binomials" together. Perhaps you've heard of the "FOIL method." If so, use it here.
y^2 + 3y - 6y - 18. Combining the middle terms, we get y^2 - 3y - 18. This is the simplest form of the product of <span>(y+3)(y-6). Done.</span>
