Answer:

12y² + 16xy -12x -29y + 15

Step-by-step explanation:

(4y - 3)(2x · 2 + (3y - 5))

multiply 2x with 2

(4y - 3)(4x + 3y - 5)

distribute (or foil) 4y - 3 into 4x + 3y -5

16xy + 12y² - 20y - 12x - 9y + 15

combine like terms

16xy + 12y² - 29y - 12x + 15

rearrange to the correct order

12y² + 16xy -12x -29y + 15

The accompanying table shows the number of bacteria present in a certain culture over a 4 hour period, where x is the time, in h
Vlad [161]

Answer:

Step-by-step explanation:

I really hope you know how to use your calculator to find regression equations, because in this forum it is impossible to teach you how to do that. I ran the data through my calculator and got the exponential equation as

y=1963.56(1.14)^x which means at 4 hours, we started with 1963 bacteria and it is growing at a rate of 114% each hour. Since we started out with an x value of 0, and that value represents the number of bacteria after 4 hours, then time 0 is 4 hours, which means that time 12 is 16 hours. We replace the x in the equation with a 12 and do the math:

y=1963.56(1.14)^{12 which gives us, in the end,

y = 9460
