If two variables are in direct proportion, then as one increases, the other increases, and as one decreases, the other decreases. An example: If you're working, the amount of money you make (variable y) is in direct proportion to how many hours you work (variable x). The more hours you work, the more money you make, and vice versa. You can put these into the equation y = kx, where k is a constant rate at which x and y are directly proportional.
<span>If two variables are in inverse proportion, then as one increases, the other decreases, and vice versa. For example: if you take unpaid vacation from work, the number of days taken off (variable x) is in inverse proportion to the amount of money you make (variable y). The more vacation you take, the less money you'll make, and vice versa. You can put these into the equation y = k/x, where k is a constant rate at which x and y are inversely proportional.</span>
Answer:
2x^2- 8x
Step-by-step explanation:
2x(x-4)
distribute; multiply parenthesis by 2 x
2x * x-2x *4
calculate products
2x^2- 8x
It is table 3.
It’s the only one that has an equal division each time
(6/3) = 2
(10/5) = 2
(14/7) = 2
She traveled 11 floors.
Explanation:
Wanda stepped onto an elevator at the 8th floor after that comes the 7th floor, 6th floor, 5th floor, 4th floor, 3rd floor, 2nd floor, 1st floor and then ground floor . Hence from 8th floor to ground floor Wanda traveled 8 floors. After ground floor she travels 3 floors more that is -1,-2,-3 . Hence here she travels 3 floors underground. Therefore, the total number of floors traveled by Wanda are 8 floors+3 floors= 11 floors.
