Real numbers x and y satisfy x + xy^2 = 250y, x - xy^2 = -240y. Enter all possible values of x, separated by commas.

agasfer [191]

Answer:

-35,35,0

Step-by-step explanation:

Let's organise our information :

x+xy²=250y
x-xy²= -240y

Now let's add them together :

x+xy²+x-xy²=250y-240y
2x=10y
x=5y ⇒ y= x/5

Let's replace y by x/5 in the first equation :

x+x*(x/5)²=250*(x/5)
x+ (x∧3)/25 = 50x
49x-(x∧3)/25=0
x(49-(x²/25))=0
x=0 or 49-(x²/25)=0
x=0 or 49= x²/25
x=0 or x²=1225
x=0 or x= $\sqrt{1225}$ or x= - $\sqrt{1225\\}$
x=0 or x=35 or x= -35

so x=[0,35,(-35)]

By selling goods for $540, a trader makes a profit of 8%. She reduces her prices to $515. What is her percentage profit now?

dybincka [34]

Answer:

Her percentage profit is 3%

Step-by-step explanation:

In the case of 8% profit,

If the purchasing price is $100, the selling price is = $100 + $8 = $108

Now,

If the selling price is $108, the purchasing price is $100

If the selling price is $1, the purchasing price is $100/$108

If the selling price is $540, the purchasing price is ($100*$540)/$108 = $500

Again,

If she reduces the selling price to $515, the profit will be ($515-$500) =$15

Now,

If the purchasing price is $500, the profit is = $15

If the purchasing price is $1, the profit is = $15/$500

If the purchasing price is $100, the profit is = ($15*$100)/$500 = 3%

ch4aika [34]

Answer:

a) 12/24 * 11/24*10/24

b) 1 - 12/24 * 11/24*10/24

c) 12/24 * 11/24 *12/24

Step-by-step explanation:

Total number of bottles = 12 + 5+7 = 24

a. The probability that all (exactly three) bottles are strawberry flavored is: 212

12/24 * 11/24*10/24

b. The probability that at least one of the three bottles are strawberry flavored is:

1 - P (no strawberry bottle)

1 - (12/24*11/24*10/24)

c. The probability that exactly 2

12/24 * 11/24 *12/24
