Answer:
and 
Step-by-step explanation:
The equation of curve is
We need to find the equation of the tangent line to the curve at the point (-3, 1).
Differentiate with respect to x.
![2[2(x^2+y^2)\frac{d}{dx}(x^2+y^2)]=25(2x-2y\frac{dy}{dx})](https://tex.z-dn.net/?f=2%5B2%28x%5E2%2By%5E2%29%5Cfrac%7Bd%7D%7Bdx%7D%28x%5E2%2By%5E2%29%5D%3D25%282x-2y%5Cfrac%7Bdy%7D%7Bdx%7D%29)
The point of tangency is (-3,1). It means the slope of tangent is 
.
Substitute x=-3 and y=1 in the above equation.
Divide both sides by 130.
If a line passes through a points 
with slope m, then the point slope form of the line is
The slope of tangent line is 
and it passes through the point (-3,1). So, the equation of tangent is
Add 1 on both sides.
Therefore, and .
Answer:
add the amount of the bags. you will end up with 38.70 Oz. the subtract the number from the total and you ger 19.30 Oz. the box weighs 19.30 oz.
it will be twelve and thirty eight hundredths
