Answer

Explanation:

Step1: Substitute (x = 1) into the equation

Given the equation (y=7x + 64), when (x = 1), we have (y=7\times1+64).

Step2: Calculate the value of (y)

[ \begin{align*} y&=7\times1 + 64\ &=7+64\ &=71 \end{align*} ] Here, (x) represents hours spent on homework in a week and (y) represents the expected quiz score. So when (x = 1) (1 hour of homework in a week), (y) (the value we calculated) is the expected quiz score.

Answer:

A student's expected quiz score if they spent 1 hour on their homework.
