What are the roots of the equation x^2 + -9=0

Mathematics
1 answer:
Anna35 [415]3 years ago
3 0

Answer:

x = 3 or x = -3

Step-by-step explanation:

If x^2 - 9 = 0 we transfer 9 to the right side of the equation and it's change negative sign to positive while doing so

now we have x^2 = 9 the square of a number must be equal to a positive number in real numbers

but the root can be either negative or positive so we say x = 3 or x = -3

The spinner is divided into eight equal sections marked with eight different colors what situation could be represented by the s
meriva
I believe the answer you looking for is Probability.

This means that if someone spinned that wheel, they have a probability of getting the color they need.

For instance,
Let's say this wheel had the colors red, orange, yellow, green, blue, indigo, purple, and pink.
If I wanted the color red on the spinner, I have a 1/8 chance to spin the color red. I have a 7/8 chance of NOT spinning red. However, let's say the wheel had 4 colors that were pink and 4 colors that were blue. If I wanted to spin the color pink, I would have a 4/8 chance OF spinning it and a 4/8 chance of NOT spinning it. 4/8 is also equivilant to 1/2.

I hope this helps you understand!!

The minimum point on the graph of the equation y = f(x) is (-1, -3). What is the minimum point
vladimir1956 [14]

Answer:

(4, -3)

Step-by-step explanation:

the equation f(x-5) is a translation of the equation f(x) by 5 units to the right.

So, if all points of the equation f(x) are shifted 5 units to the right, the minimum point of the graph is also shifted 5 units to the right, so to find the minimum point of y = f(x - 5), we just need to sum 5 units to the x-coordinate:

Minimum point = (-1 + 5, -3) = (4, -3)

So the minimum point of y = f(x - 5) is (4, -3).
