In anatomy class, test scores were determined to be 20 times the number of hours, h, the student studied plus 4. Which of the following functions best describes a students test score depending on the number of hours, h, that the student studies.

20h + 4

Explanation:

Based on the information given in the question, the function that best describes a students test score depending on the number of hours, h, that the student studies will be:

= (20 × h) + 4.

= 20h + 4

Let's assume the student studied for 3 hours, the test score will be:

= 20h + 4

= 20(3) + 4

= 60 + 4

= 64.

it would take 95 years for that supernova to be visible on earth, so the year would be about 2113. i hope i did my calculation right.
