Answer:
The answer to your question is y = -8/9x - 22
Step-by-step explanation:
Data
The slope is the coefficient of "x" and the y-intercept is the number after the "x"
y = -8/9x - 22 Slope -8/9 and y-intercept = -22
y = 8/9x - 22 Slope 8/9 and y-intercept = -22
y = -8/9x + 22 Slope -8/9 and y-intercept = 22
y = 8/9x + 22 Slope 8/9 and y-intercept = 22
The line that has both slope and y-intercept negative is the first choice.
Answer:
A. 56.52
Step-by-step explanation:
Circumference = 2πr
Radius is half of the diameter, but 2 times radius is also simply the diameter. Therefore, the solution of the problem would be 18 times π. In this case, we can round π to 3.14, and 18 times 3.14 is 56.52.
Answer:
8.8%
Step-by-step explanation:
Given that,
Cross-price elasticity between airline tickets and gasoline = 2.2
Price of the gasoline increases by 4%.
Therefore,
Cross-price elasticity = Percentage change in the quantity demanded of airline tickets ÷ Percentage change in the price of gasoline
2.2 = Percentage change in the quantity demanded of airline tickets ÷ 4%
2.2 × 4 = Percentage change in the quantity demanded of airline tickets
8.8% = Percentage change in the quantity demanded of airline tickets
