Your question: Which equation has solution x = -3?
I'd like you to know: I couldn't find any answer that exactly answered X=-3, although there is an answer similar to. But if it was accidental, this would be the most <em>correct </em>answer.
Answer: A) 2x - 7 = -1
|Step-by-step explanation|
- 2x - 7 = -1 = x=3
- 3x + 8 = 1 = x=-7/3
- x + 8 = 10 = x=2
- 11 (2x-6) = -6 = x=30/11
Answer:
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
They are not because the left side is 52, while the right side is 0.
Answer:
A=SqRt(c^2-b^2)
Step-by-step explanation:
a^2 + b^2 = c^2
rearrange to solve for a^2
a^2= c^2-b^2
take the square root of each side
a= square root (c^2-b^2)
I remember CUP -- concave up positive. Here we have a leading coefficient that's negative, so the cup is upside down, the parabola opens down, an arch not a bowl.
