My friend Elentine purchased 9 Naxvips for $2 each and some toys for $8 each.
1 answer:
The equations to model the relationship between Elentine's naxvips (x) and toys (y) is: Total cost = 18 + 8y
<em><u>Solution:</u></em>
Let "x" be the number of naxvips bought
Let "y" be the number of toys bought
From given,
Cost of each naxvip = $ 2
Cost of each toy = $ 8
My friend Elentine purchased 9 Naxvips for $2 each and some toys for $8 each.
Thus according to given we frame a equation as:
Total cost = 9 naxvips x 2 + y x 8
Thus total cost spend is (18 + 8y) dollars

The equation of a parabola whose vertex is (0, 0) and focus is (1 / 8, 0) is equal to x = 2 · y².
<h3>How to derive the equation of the parabola from the locations of the vertex and focus</h3>
Herein we have the case of a parabola whose axis of symmetry is parallel to the x-axis. The <em>standard</em> form of the equation of this parabola is shown below:
(x - h) = [1 / (4 · p)] · (y - k)² (1)
Where:
- (h, k) - Coordinates of the vertex.
- p - Distance from the vertex to the focus.
The distance from the vertex to the focus is 1 / 8. If we know that the location of the vertex is (0, 0), then the <em>standard</em> form of the equation of the parabola is:
x = 2 · y² (1)
