A company's profit (in millions of dollars) can be represented by x^2-6x+12, where x is the number of years since the company st
Sergeu [11.5K]
The function that models the profit of the company in million of dollars is:

P= x^{2} -6x+12

where x represents the number of years since the company started. We want to find when the profit of the company was $4 million. Setting P as 4 in above equation, we can find the value of x when the profit was $4 million.

4= x^{2} -6x+12 \\  \\ 
 x^{2} -6x+8=0 \\  \\ 
 x^{2} -2x-4x+8=0 \\  \\ 
x(x-2)-4(x-2)=0 \\  \\ 
(x-2)(x-4)=0 \\  \\ 
x=2, x=4

Thus, we can conclude that the profit of the company was $4 million in 2nd and 4th year

-7+ 5Y = -37 simplify your answer as much as possible
irinina [24]

Answer:

y = -6

Step-by-step explanation:

To simplify this equation as much as possible, we have to get the variable y by itself.

To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.

-7 + 7 + 5y = -37 + 7

The 7s cancel out on the left side because -7+7 = 0 and so we are left with,

5y = -30

Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.

5y/5 = -30/5

y = -6
