Answer:
There are no solutions to this equation because we will end up in 0=0 or if we do other methods, you will get something = 0
Hope it helps :)
Answer:
The slope for the line is 2
2 cubed. Cubed also means multiply so enjoying by itself times. So, 2 * 2 = 4 * 2 = 8.
2 cubed = 8
Two prime numbers greater than 25 and less than 35.
Let p be a prime that satisfies
25 ≤ p ≤ 35.
The set of prime numbers:
P = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, ... }
There are only two prime numbers greater than 25 and less than 35:
Answer: {29, 31}.

<span>1)
11x+5y=20
2x+5y=-25
multiply the second equation by - 1 and add the result with the first equation:
11x + 5y = 20
- 2x - 5y = 25
-------------------
9x = 45
=> x = 45 / 9
=> x = 5
Replace in </span><span>2x+5y=-25
=> 2(5) + 5y = - 25
5y = - 25 - 10
5y = - 35
y = - 35 / 5
y = - 7
2)
3x+7y=-21
3x-7y=63</span>
Add the two equations:
3x + 3x + 0 = - 21 + 63
6x = 42
=> x = 42 / 6
=> x = 7
Replace in <span>3x-7y=63
3(7) - 7y = 63
=> 7y = 21 - 63
=-> 7y = - 42
=> y = - 42 / 6
=> y = - 7</span>
