(x - 1/6)(x - (-2/3)) = 0
(x - 1/6)(x + 2/3) = 0
x^2 + 2/3x - 1/6x - 1/6(2/3) = 0
x^2 + 1/2x - 1/9 = 0
18x^2 + 9x - 2 = 0
Slope-intercept formula is y2-y1 / x2 - x1 | Grab any two points from the table, and plug them in, for example I'll use the first two (1,5) and (2,11) | 11-5 / 2-1 = 6 = The slope is 6, next you'll want to grab one of the points in the pair, I'll use (1,5) for this example, y-5=6(x-1) | distribute 6 to x and -1, and add 5 to both sides to get y by itself, final answer is y=6x-1
5.58 + 9 = 14.58
5.04 + 6 = 11.04
2x2 - 16y2 + 9xy
(the 2 to the right of the x and y are small numbers i forgot what dey are called lol)
Answer:
Table
Bottles Price($)
3 78
6 156
9 234
From that you can find the unit price: 78 / 3 = 156 / 6 = 234 / 9 = 26.
That means that the unit rate of this fragance is $26.
If you call x the number of bottles the equation is
Price = unit rate * number of bottles = 26x.
Now compare this information with that on your graph to compare the unit rates.
This can help you fo find the unit rate in from your grpah: the unit rate is the slope of the line =
[change in y-coordinate] / [change in the x-coordinate]
