Answer:
Two subsets that form set of real numbers
You can take positive numbers and negative numbers subset
One subset become (- infinity,0]
other subset (0, infinity)
The answer is y=(1/20)x^2
Answer: 231
<u>Explanation:</u>
Liwen Celina
5x 6x
5x - 21 =
6x
5x - 21 = 4x
<u>-4x +21</u> <u>-4x +21 </u>
x = 21
Liwen: 5x = 5(21) = 105
Celina: 6x = 6(21) =<u> 126</u>
Total: 231
If they are equal then,
5x-3=2x+25
3x=22
X=7 +1/3=7.(3)
