Answer:

y = -2 ( (x^2) + (2*x*5) + (5^2)) - 30

y = -2 ( x^2 + 10x + 25) - 30

y = -2x^2 - 20x - (2*25) - 30

y = -2x^2 - 20x - 50 - 30

y = -2x^2 - 20x - 80

Equations for the numbers of pairs of socks (s) and handkerchiefs (h) can be written as
3s +2h = 1.45
2s +5h = 1.75

if you decrease by a given percent and then increase by the same percent, will you be back where you started? how do you know

quester [9]

Lets pick a random number, like 50. Lets decrease and increase it by 50%. After the decrease, you will get 25, but when you increase it by 50%, it's only 37.5. No, because when you decrease it, you have a smaller base, so it increases less than it decreases. 50% of 100 is 50, but 50% of 50 is 25. You can see there is a significant difference.
