Its an ellipse.
3 (x+7)^2+2 (y-2)^2-6 = 0
Answer:
20/3
Step-by-step explanation:
5/k=15/20
5/k=3/4
5 x 4/3 = k
k=20/3
Use point-slope formula---> y-y1=m(x-x1)
Let y1 equal -9, let x1 equal -10, and let m equal 3
Plug in and solve
y-(-9)=3(x-(-10)
y+9=3(x+10)
y+9=3x+30
Subtract nine from both sides
y=3x+21(This is slope form, i might have gone too far)
Answer:
18%
Step-by-step explanation:
Since the original price is $78 then this is the original 100% of the price. The new price will be marked up x percent and be $92. To find the new price set up a proportion with these values:

Solve for the original price by cross multiplying numerator with denominator.
x(78) = 92(100)
78x = 9200
x= 117.9 = 118%
This is 18% more or over the original price.
