1) The scatter plot shows the amount of rainfall received each year from 2000 - 2008 in Tennessee. Draw the line of best fit for the scatter plot.
2) A scatter plot showing the cost of refrigerators based on their capacity is shown below. The scatter plot has a line of best fit drawn. Predict how much a refrigerator with a capacity of 8 cubic feet would cost. Cost is money, so make sure you use the correct units.
3a) Make a scatter plot for the data presented in the table
3b) Draw the line of best fit on your scatter plot above.

step-by-step explanation:

the picking cards and marbles hope this

x³ - 13x + 12

step-by-step explanation:

if you are familiar with the distributive property

a(b+c) = a·b + a·c

then you can apply this here with the binomials.

since multiplication over the real numbers is commutative, we can multiply these binomials in any order. suppose we want to focus on the product (x - 1)(x + 4)

using the distributive property, we can distribute (x - 1) into (x+4):

(x - 1)(x + 4) = x(x - 1)+ 4(x - 1)

and then we apply the distributive property again:

  = x² - x + 4x - 4

combining like terms -x and 4x, we get that

  = x² + 3x - 4

hence we have that (x - 1)(x + 4) = x² + 3x - 4. in this original product, this means that

  (x - 1)(x + 4)(x - 3) = (x² + 3x - 4)(x - 3)

now we can take (x - 3) to the front

  = (x - 3)(x² + 3x - 4)

and then distribute (x-3) inside

  = x²(x - 3) + 3x(x - 3) - 4(x - 3)

now distribute again

  = x³ - 3x² + 3x² - 9x - 4x + 12

and combine like terms to get a final answer of

  = x³ - 13x + 12
