Anonymous users2024-02-13Do what you should do and be moved by your actions. Affection is a process of reciprocity. The necessary communication is a must.
Solve problems and conflicts through communication. If only one party is willing or active, such feelings are still very confused. When you need to make a decision, be simple.

The skin is pure, a+b=-4, ab=6
3a+3b-2ab=3(a+b)-2ab=-12-12=-24
a^2+b^2=(a+b)^2-2ab=16-12=4

10x²＋280x－1600
Its axis of symmetry is x -280 [2 (-10)] 14 at this time y 360
When the selling price is set at 14 yuan, the maximum profit in a single day is 360 yuan.

Anonymous users2024-02-10Profit per piece = 10-8 + x = 2 + x
Sales = 100-10x
y=(2+x)(100-10x)=-10(x-4)2+360 Because -10<0, the maximum value of y is 360 when x=4

Anonymous users2024-02-09Sold per day: 100-10 (x-10).
Profit per day: y = (x-8)[100-10(x-10)] Simplified to obtain: y = -10x 2 + 280x - 1600 = -10(x-14) 2 + 360
It can be seen that when x 14, the function y obtains a maximum value of 360
Answer: When the selling price is set at 14 yuan, the maximum profit per day is 360 yuan.
