What is the image of the point (3,-8) after a rotation of 90° counterclockwise about the origin?

Mathematics
1 answer:
yuradex [85]3 years ago

Answer:
(8,3)
Step-by-step explanation:
When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.
When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).
y is -3, and -(-3) is just 3, since two negatives make a positive.
x just remains x, but it's in a different position.
This makes the new coordinate .
Hope this helped!

Multiply the trinomial x^2+xy+y^2 times the binomial x-y and simplify.
Natalija [7]
Multiply then simplify, that's doing the same work twice...anyway

x^3+x^2y+xy^2-x^2y-xy^2-y^3

x^3-y^3  which if factored is:

(x-y)(x^2+xy+y^2)  which is what you started with :)

What are 3 consecutive numbers that is the sum of -27.please be right.use odd numbers
qaws [65]
You're asking for three consecutive odd numbers, then
Let, the numbers = x, x+2, x+4

It is given that, x + x+2+ x+4 = -27
3x + 6 = -27
3x = -27 - 6
x = -33/3
x = -11
Then, x+2 = -9 & x+4 = -7

In short, Your Numbers would be: -7, -9,-11

Hope this helps!

The graph shows the total number of inches of snow after different numbers of hours.
erastova [34]

Answer:

A, is the answer.

Step-by-step explanation:

If you take two points and then find the slope between them you'll find that it is 1.5.

You could also make a T-chart or plug in the x coordinates into each possible equation and see which one matches the corresponding y coordinate.
