Answer:
She sold for $4683.33
Step-by-step explanation:
For a sales of $1000 she is paid 7.5% which is equivalent to $75.
Since she earned $517 , her total sales was more than $1000.
Let she had a sales of $(1000+x).
Then her commission would be $75 + 12% of $x .
But her total commission was $517.
Then commission from sales after she sold for $1000 = $(517 - 75)
= $442
This is also equal to 12% of x.
![0.12 \times x[\tex] = $442x = [tex] \frac{442}{0.12}](https://tex.z-dn.net/?f=0.12%20%5Ctimes%20x%5B%5Ctex%5D%20%3D%20%24442%3C%2Fp%3E%3Cp%3Ex%20%3D%20%5Btex%5D%20%5Cfrac%7B442%7D%7B0.12%7D)
x = $3683.33
Hence she sold for $4683.33
The equation of a circle with a center of (h,k) with a radius of "r" is

looking at the given equation,
5x^2 +5y^2=20
divide 5 to both sides to get
x^2+y^2 =4
now compare that to the equatio of a circle shown above
5x^4 - 3x^3 + 6x - (3x^3 + 11x^2 - 8x) =
5x^4 - 3x^3 + 6x - 3x^3 - 11x^2 + 8x =
5x^4 -6x^3 - 11x^2 + 14x <== yep, I got the same thing
