Answer:

X > 10

Step-by-step explanation

The question says more than 132. So lets say Jinny has to earn $135 to meet her target.

132 - 117 = 18. She needs to earn 18 more dollars

18/ 1.50 = 12. She needs to sell 12 more to make 18 dollars

X > 10 says she needs to sell more than 10. Which is true

Find dy/dx by differentiating implicitly x^2y+3xy^3-x=3

AleksandrR [38]

$\dfrac{\mathrm d}{\mathrm dx}\left[x^2y+3xy^3-x\right]=\dfrac{\mathrm d}{\mathrm dx}[3]$
$2xy+x^2\dfrac{\mathrm dy}{\mathrm dx}+3y^3+9xy^2\dfrac{\mathrm dy}{\mathrm dx}-1=0$
$(x^2+9xy^2)\dfrac{\mathrm dy}{\mathrm dx}=1-2xy-3y^3$
$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{1-2xy-3y^3}{x^2+9xy^2}$
