Question

Claire's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This relationship can be represented by the equation y represented by the equation y = 56 + 7.1x, where y represents the expected quiz score and x represents hours spent on homework that week. What is the meaning of the x-value when y = 92?
the change in expected quiz for every additional one hour students spend on their homework.

a student's expected quiz score if they spent 1 hours on their homework.

the number of hours a student should spend on their homework to expect a score of 92 on the quiz.

a student's expected quiz if they spent 92 hours on their homework.​

Answer 1

Answer: t = 5.7 hours

Step-by-step explanation:

y=56+7.1x where x is the time spent studying.  If y=92, this equation would preduct that the student spent t hours studying.  Find t:

92=56+7.1x

36=7.1t

t = 5.07 hours to achieve the 92 score.
