Explain how you calculate the constant of variation.

Mathematics

Answer:Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3. Thus, the equation describing this direct variation is y = 3x.

Step-by-step explanation:The constant of variation means the relationship between variables does not change. When we want to identify the constant of variation for an equation, it is helpful to refer to one of the following formulas: xy = k (inverse variation) or y/x = k (direct variation), where k is the constant of variation.

An elevator has a maximum of 2,000 pounds. There are 5 people on the elevator with the combined weight of 821 pounds. Write an i
kati45 [8]

Answer:

2,000 ≥ 821+x

Step-by-step explanation:

it is said that the maximum weight the elevator could hold is 2,000, so the weight in the elevator should be 2,000 or less then 2,000.

It is said that already 5 people are inside with a weight 821, in this case we only care about the weight

the inequality will look: 2,000 ≥ 821

now they asked us how much more weight can the elevator can hold

lets make (x) represent the extra weight

x= extra weight

the equation will be 2,000 ≥ 821+x
