Answer: x = 0

Step-by-step explanation:

Subtract 6x^3+29x^2+47x+28 from both sides:

(2^2 + x + 4) (x - 7) - 6x^3+29x^2+47x+28

(6x^3+29x^2+47x+28)-6x^3+29x^2+47x+28

= -4x^3 - 14x^2 - 36x = 0

Now factor the left side:

-4x^3 - 14x^2 - 36x = 0

(-2x) (2x^2 + 7x + 18) = 0

Now set the factors equal to 0

-2x = 0 or 2x^2 + 7x + 18 = 0

x = 0

Joyce paid $170 for an item at the store that was 25 percent of the original price. What was the original price?
igor_vitrenko [27]
If it was 25% off, then she paid 75% for it

75% of the original price is 170
0.75x = 170
x = 170 / 0.75
x = 226.67 <== original price

An investment promises a return of 12% per year. Brody wants to figure out how much money he will have if he invest $1000 for 5,
jeka57 [31]

the exponential function f(x) =1000(1.12)^x

he invest $1000 for 5, 10, 15 years

5 years,

To find the amount of money he have , we plug in 5 for x and find out f(5)

f(x) =1000(1.12)^x

f(5) =1000(1.12)^5 = 1762.34

The amount of money he have after 5 years is 1762.34

10  years,

To find the amount of money he have , we plug in 10 for x and find out f(10)

f(10) =1000(1.12)^10 = 3105.85

The amount of money he have after 10 years is 3105.85

15  years,

To find the amount of money he have , we plug in 15 for x and find out f(15)

f(15) =1000(1.12)^15 = 5473.57

The amount of money he have after 15 years is 5473.57

f(5) = 1762.34

f(10) = 3105.85

f(15) = 5473.57
