Answer:
3x^2 - 6x - 9
Step-by-step explanation:
In order to make the function have zeros at -1 and 3 it needs to factor into:
<u>To make that:</u>
3x^2 - 6x - 9
(3x - 9)(x + 1)
<u>To check:</u>
3x - 9 + 9 / 3 = 0 + 9 / 3
x = 3
x + 1 - 1 = 0 - 1
x = -1
So, it is correct.
Answer: 3x^2 - 6x - 9
Answer:
There are 2 different ways, depending on the amount of data given;
<em>1st way:</em> When only the line on the graph is given (Without any coordinate points given) then the slope could be found out with the formula of <u>Rise/Run, or Change in y / Change in x</u>
<em>2nd way: </em>When a line and 2 coordinate points are given, the the formula that would be used is:<u> </u>
<u>, where X₁ and Y₁ are the coordinate points of the 1st given point, and X₂ and Y₂ are the coordinate points of the 2nd given point.</u>
Hope this helps!

You should get 23.999976
So, now just round it and you should get 24 as your final answer.
Answer:
900 people preferred hamburgers.
Step-by-step explanation:
540/x=60/100
cross multiply
60x=54,000 then
60x/60=54,000/60
x=900
so 900 people preferred hamburger
