Mr. Brown needs to price items that must be sold within 90 days, and he has two options. In option A, Mr. Brown prices items at $225 and gives $1.00 off the price each day that the item does not sell. In option B, he prices items at $250 and gives $2.00 of the price each day that the item does not sell Write and solve a system to determine when the two options yield the same price.

The two options yield the same price at 25 days.

Step-by-step explanation:

With the information provided, you can say that the option A would be equal to option B, which would be:

225-1x=250-2x, where x is the number of days that the item does not sell

Now, you can solve for x:

-1x+2x=250-225

x=25

According to this, the answer is that the two options yield the same price at 25 days.

3, nah jk it's 2

step-by-step explanation:

it is 3 cause i'm sanic

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
