A center of rotation is a point where a plane rotates
Answer:
Step-by-step explanation:
First you would see how many times 3 would go into 22 and it would be 7 with a remainder of 1. Then you would do 7 times 3 which is 21. And 22 minus 21 is 1. Then your answer would be 7 with a remainder of 1. If you don't want a remainder, and you want a decimal then you would add a decimal point after the 22 and then add a 0. You would bring down the zero and then the remainder of one would be 10 then you would see how much 3 goes into 10, and it only goes 3 times. Your answer would be 7.3 with a remainder of 1, If you keep going you will see it becomes a repeating decimal. *Hope it helped*
Answer:
x = 5 ± 
Step-by-step explanation:
Given
x² - 10x + 25 = 17 ← left side is a perfect square, thus
(x - 5)² = 17 ( take the square root of both sides )
x - 5 = ± ( add 5 to both sides )
x = 5 ±
Thus
x = 5 -
x = 5 +
Answer:
(3.25, 1.5)
Step-by-step explanation:
<em><u>First, turn the 2nd equation into y=mx+b form:</u></em>
у+ 2x = 8
<u> -2x -2x</u>
y = -2x + 8
<u><em>Next Substitute:</em></u>
З(-2x+8) - 2x = -2
-6x + 24 - 2x = -2
-8x + 24 = -2
<u><em>Then simplify:</em></u>
-8x + 24 = -2
<u> -24 -24</u>
-8x = -26
x = 3.25
<em><u>Lastly, substitute x into any one of the original equations:</u></em>
y + 2 (3.25) =8
y + 6.5 = 8
<u> - 6.5 - 6.5</u>
y = 1.5
please give me brainliest i worked hard on this :,)
and its 1000% correct, i checked it i promise
C. y= [25,100]
you need brackets because the points actually touch the number
