Answer:
For a "want" like a TV, she should have an amount in the spending section. She is trying to save, so she shouldn't waste her money on something that is not a necessity. She still has 90% left of her checks, so she has that money. She could use that.
The answer is (x, y) = (-1, 4) hope this helped
N= 1
1(1-1)-4 = 0-4 = -4
n=2
2(2-1)-4= 2-4= -2
n=3
3(3-1)-4= 6-4= 2
n=4
4(4-1)-4= 12-4= 8
If we are ordering these from least to greatest, it would be as follows:
-7, -1, 1, 7
Remember that the 'smaller' negative numbers are those that are further away from 0.
Then, if we need to add inequality signs, it would be as follows:
-7 < -1 < 1 < 7
Basically, we are saying that -7 is less than -1, which is less than 1, which is less than 7.
Hope this helps!! :)
