What is the coordinate for the image of point H( -1, -5) under a 90° clockwise rotation about the origin?
Answers
The coordinate for the image of point H( -1, -5) under a 90° clockwise rotation about the origin is, (- 5, 1)
What is Coordinates?
A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
The coordinate of the point H( -1, -5)
Now, The rule for the 90° clockwise rotation about the origin is,
(x, y) = (y, - x)
Hence, The coordinate for the image of point H( -1, -5) under a 90° clockwise rotation about the origin is,
(- 1, - 5) = (- 5, 1)

I know how to do algebra, and I could write how to do it for you. But If I start writing and keep going until I explain to you how to do algebra, do you know what you'd have here ? You'd have an algebra book, just like the one you use in school.
If it were possible to explain algebra in a few paragraphs, or even in a few pages, then that's what you would use in school to learn it, instead of a book. And if it could be explained in a few minutes, or even in a few hours, then teacher would explain it all at the beginning of the year, and then you'd have the rest of the whole year to just practice it and get really good at it.
You use a book, and you spend a whole year learning it, because that's what it takes.
I shall now reveal to you the secret hidden sneaky tricks of how to do algebra:
(If you want to print this and stick it on the refrigerator, you have my full permission.
This method is so good that it even works with a lot of other subjects too.)
-- Go to class every day.
-- As you're sitting down, turn off your cellphone and wrap up your gum.
-- Stay awake in class.
-- Listen to what the teacher is saying. In your mind, make pictures of what it means.
-- When you get a homework assignment, write it down.
-- Make a place at home where you always do your homework. Make it a place where other people aren't running through. While you're there doing homework, turn off the radio and your cellphone, and take the buds out of your ears.
-- On the same day you get the homework assignment, when you're home, sit down in the place where you do your homework, and work ALL of the examples in the assignment. (That may mean that you can't go out that night.)
-- If there's something you just don't get, ask the teacher for a time to sit down together and work on it together until you understand it. That's part of the teacher's job.
If you're building a brick house, and you leave out some bricks near the bottom and keep stacking bricks above the hole, the part above the hole could come crashing down any minute, and there's no way to go back later and try and fill in the hole.
Algebra is exactly like that. Each day or two, in class and in homework, you have to use what you learned in thelast day or two. If there's a hole there, it's awfully tough to build anything on top of it. If you don't understand how to do something, or you blow off a couple of homeworks, there is no way to go back and catch up later.
Follow my method, and algebra is easy !

Side a, b and c are 10cm , 6cm , 12cm
Given that;
Side a = 4 + Side b
Side c = 2(Side b)
Perimeter of triangle = 28 cm
Find:
Length of each side
Computation:
Assume;
Side b = q
Side a = 4 + q
Side c = 2q
So,
Perimeter of triangle = 28 cm
q + 4 + q + 2q = 28
4q = 24
q = 6
Side a = 10 cm
Side b = 6 cm
Side c = 12 cm

-1,-3,-7,-9,-21,-27,-49,-63,-81,-147,-189,-441,-567,-1323,-3969 is this what you mean
Final answer:
In this Mathematics problem, you're searching for two numbers that, when multiplied, equal 3969 and, when added, equal 126. By factoring 3969, we find that the numbers 63 and 63 meet both criteria.
Explanation:
This Mathematics problem falls under factoring in Algebra. You are trying to find two numbers that multiply to 3969 (the product) and add up to 126 (the sum). The numbers you're looking for are 63 and 63. Let's see why.
First, factor 3969. The factors of 3969 are 1, 3, 9, 27, 81, 147, 441, 1323, and 3969. Looking at these factors, we see that only 63 and 63 multiply together to give 3969.
Now, check if they also add up to 126. Indeed, 63 + 63 equals 126, confirming that these are the two numbers you're looking for.
