The second store price is cheaper beacuse 16% of 573 gives off $91.68 and when u do that u get $481.32 so 458.40 is cheaper.
we have the equation
2(x-4)=6x+4
solve for x
Apply distributive property left side
2x-2(4)=6x+4
2x-8=6x+4
Group terms
6x-2x=-8-4
combine like terms
4x=-12
divide by 4 both sides
x=-12/4
<h2>x=-3</h2>
Answer:
slope is change in rise(y) over change in run (x), change in y here is 36 and change in x is 2, slope is 36/2=18
The x-value of the vertex of the given parabola is x = 5, so the correct option is b.
<h3>
How to get the x-value of the vertex?</h3>
If we define the parabola by f(x), by looking at the table, we can read:
So, notice that:
f(2) = f(8).
Then the x-coordinate of the vertex is the midpoint between 2 and 8.
x = (2 + 8)/2 = 5
The x-value of the vertex of the given parabola is x = 5, so the correct option is b.

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]
