If \( x=2.1 \) when \( y=7.2 \) find \( x \) when \( y=7.56 \)

To find \( x \) when \( y = 7.56 \), we can assume a linear relationship between \( x \) and \( y \). Given the values \( x = 2.1 \) when \( y = 7.2 \), we can set up a proportion based on the change in \( y \). First, we calculate the change in \( y \): \[ \Delta y = 7.56 - 7.2 = 0.36 \] Next, we find the ratio of the change in \( x \) to the change in \( y \). Since we only have one point, we can assume a linear relationship and use the known values to find the slope: \[ \text{slope} = \frac{\Delta x}{\Delta y} \] We can express \( x \) in terms of \( y \) using the point we have: \[ \frac{x - 2.1}{y - 7.2} = \frac{2.1 - x}{7.2 - y} \] However, since we only have one point, we can also use a simple linear interpolation. We can find the change in \( x \) corresponding to the change in \( y \): Assuming a linear relationship, we can find the change in \( x \) per unit change in \( y \): 1. Calculate the change in \( y \) from \( 7.2 \) to \( 7.56 \): \[ \Delta y = 7.56 - 7.2 = 0.36 \] 2. We can find the ratio of \( \Delta x \) to \( \Delta y \) using the known point. Since we don't have another point, we can assume a small linear change. Let's assume that the change in \( x \) is proportional to the change in \( y \): If we assume that the relationship is linear, we can find \( x \) when \( y = 7.56 \) using the ratio of the changes: \[ \frac{\Delta x}{\Delta y} = \frac{2.1 - x}{7.2 - y} \] However, we can also directly calculate \( x \) using a simple linear interpolation: Let \( k \) be the change in \( x \) per unit change in \( y \): \[ k = \frac{2.1 - x}{7.2 - 7.56} \] Since we don't have another point, we can assume a small change. To find \( x \) when \( y = 7.56 \): Using the linear relationship: \[ x = 2.1 + k \cdot (7.56 - 7.2) \] Assuming \( k \) is small, we can estimate: \[ x = 2.1 + \frac{2.1 - x}{0.36} \] This gives us a linear approximation.
