Add 1 to both sides:

In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that

Under this assumption, we square both sides and we have

The solutions to this equation are

But since we can only accept solutions greater than -1, we discard
and accept
.
In fact, we have

and

which is the only solution.
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer

Yo my guy, this is really easy

Answer:
The rounded number is 10,000.
Step-by-step explanation:
Rounding means making a number simpler but keeping its value close to what it was.
The digit in the ten thousands place is 1.
The digit to its right is 2, so the digit in the ten thousands place stays the same.
Leave it the same if the next digit is less than 5, this is called rounding down. And increase it by 1 if the next digit is 5 or more, this is called rounding up
