Answer:
x = 20
y = 70
Step-by-step explanation:
Solve for x:
5x - 20 = 3x + 20
2x - 20 = 20
2x = 40
x = 20°
Solve for y:
x + y = 90°;
(20) + y = 90°
y = 90 - 20
y = 70°
Hope this helps!

Step-by-step explanation:
Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Percentage change in price = (1.2/1) - 1 = 20%
Percentage change in quantity demanded = 450/500 - 1 = 10%
-5x^4 (-3x^2 + 4x - 2) =
15x^6 - 20x^5 + 10x^4
