Answer:

48,000

Step-by-step explanation:

3,000 x 2 = 6000 (decade one)

6000 x 2 = 12000 (decade two)

12000 x 2 = 24000 (decade three)

24000 x 2 = 48000 (decade four)

PLEASE HELP I WILL BRAINLIST
PSYCHO15rus [73]

Answer:

8

Step-by-step explanation:

Since they intersect you can just solve for x and y

since y=-4x and y=x^2+2x+8, you can set -4x=x^2+2x+8

add 4x to both sides to make 0=x^2+6x+8

and factor out (x+4)(x+2)

so the solutions for x are -4 and -2

then insert the two values for x into the first equation

so y=-4(-4) and y=-4(-2)

so y=16 and y=8 when x=-4 and x=-2

so the smallest value for y in both equations is 8

Please give brainliest :)

Steps for solving 3x+18=54 are shown explain how step 1 helps solve the equation
Dennis_Churaev [7]

Answer:

The answer is x=12.

Step-by-step explanation:

First, to solve this equation you need to isolate the x variable. To isolate the variable, you must, subtract the other term from both sides. Subtracting 18 from both sides, you are left with 3x = 36. Since 3 times x = 36, dividing both sides by 3 gets you, x=12.

lubasha [3.4K]

Answer:

Dealer 2

Step-by-step explanation:

Dealer 1

Purchase price = 20500

Sales price = 25000

Profit :

((25000 - 20500) / 20500) * 100%

= 21.95%

Dealer 2 :

Purchase price = 22000

Sales price = 28800

((28800 - 22000) / 22000) * 100%

= 30.90%

The better buy is for dealer 2 has he made a higher percentage profit
