Step-by-step explanation:
9 would be ur answer....because 9 is an odd number greater then 2, but it is not a prime number
Answer:
(1, -9)
Step-by-step explanation:
4x + y = -5
8x + 3y = -19
If we have to use elimination, that means we're going to add or subtract these two whole equations by each other so that we can cancel out one of the variables.
I think that we could easily turn 4x into 8x if we multiply the top equation by 2.
4x + y = -5 ---> 8x + 2y = -10
Now put them next to each other, and subtract to get rid of the xs.
8x + 2y = -10
- 8x + 3y = -19
------------------------
0x - y = -10 - -19
-y = 9
y = -9
Plug this back in to get x.
4x + y = -5
4x - 9 = -5
4x = -5 - -9
4x = 4
x = 1
An Irrational Number is one which cannot be put into rational form (i.e. a fraction)
Pretty much, any decimal that is not in any particular order is irrational. Of this list, <span>√ 8 is the only one that generates a non-repeating decimal, so that is your irrational number.
