Answer:

x=0,3

Step-by-step explanation:

start by dividing every term by 3

x^3-3x^2+x-3

group into 2 terms

(x^3-3x^2)+(x-3)

simplify as much as you can

x^2(x-3)+(x-3)

combine terms

(x^2)(x-3)

x=3, 0

- The best method to test Zoe's claim is an observational study, as with this method it is possible to observe if the claim presents some truth to it. Observational studies are often used in testing claims like Zoe's as they allowed to have a great access to the variable that are behind a claim of that type, and so they are also more accessible.

- The set up I would use is an observational study of a great number of people, over a long period of time, that have to have<span> kale for breakfast every day, with a measurement of their cholesterol over the time. the great number and the long period of study assured that the variable subject of study is statistically represented in an optimal way. </span>

Write an equation of the line that passes through the given points.<br><br> (0,−3),(3,3)
Delicious77 [7]
I find it easiest to use slope-intercept form, or y=mx+b, to do this.

First, find the slope. 6/3 = 2/1 = 2. m = 2.

Next, find the y-intercept. In this case they gave it to you directly. b = -3.

So, the equation would be y = 2x - 3.
