That easiliy false. You can prove this by observing that all integers are, in particular, rational numbers. So, for instance, you can think of 4 as 
, so 
And obviously, you have 
It is true that the square of every rational number between 0 and 1 is smaller than the number itself.
But since not all rational numbers are between 0 and 1, the general claim is false.
20 mins: it says the answer in the graph
1 % of 9 is 0.09, multiply 0.09 by 5= 0.45 (to find 5%)
Then multiply 0.45 by 36 (3years)= 16.20
Then add 16.20 to $9= $25.20

Answer:
x=-2
y=-3
Step-by-step explanation:
-9x+4y = 6
9x+5y = -33
We will add these together to eliminate x
-9x+4y = 6
9x+5y = -33
----------------
0x +9y =- 27
9y = -27
Divide by 9
9y/9 = -27/9
y =-3
We still need to find x
9x +5y = -33
9x +5(-3) = -33
9x-15 = -33
Add 15 from each side
9x+15-15 =-33+15
9x=-18
Divide by 9
9x/9 = -18/9
x = -2
