y is inversely proportional to x. - Brainly.com
2017年2月28日 · The equation that connects y and x is y = 63/x. When x = 21, the value of y is 3. Explanation: When we say that y is inversely proportional to x, we mean that y = k/x, where k is the constant of proportionality. To find this constant, we use the given values: when y = 7, x = 9. Therefore, 7 = k/9, so the constant k is 63 (because 7 * 9 = 63).

2020年4月1日 · The value of y when x = 21 is 153/7. When y = 7, x = 9, so we know that there is a linear relationship between y and x with a slope of (9 - 0)/(7 - 0) = 9/7. This means that the equation connecting y and x is: y = 9/7 * x + b . To solve for b, we can plug in the fact that when y = 7, x = 9: 7 = 9/7 * 9 + b . 7 = 27/7 + b . b = 7 - 27/7 . b ...

The equation connecting y and x is y = 63/x. When x = 21, y = 3. Explanation: In mathematics, when we say that y is inversely proportional to x, it means y increases when x decreases and vice versa, following a specific constant ratio. In such cases, we can represent this relationship as y = k/x, where k is the constant of variation.

2021年9月12日 · If y is inversely proportional to x, this relationship can be described by the equation y = k/x, where k is a constant. Given that when y=80, x=3, we can find the constant k by multiplying the two values to get k = 80 * 3 = 240. To work out y when x=4, we use the same equation: y = k/x = 240/4, which simplifies to y = 60.
