(-7,0) and (-5,0)

Step-by-step explanation

1. 0= (x + 7)

  -7        -7

    -7=x

(-7,0)

2. 0= (x + 5)

    -5         -5

      -5=x

(-5,0)

75 combinations ~ so there's 15 novels everyone picks 5 . you take 15 * 5 and get the amount . so in this question/problem the amount of freshmen is irrelevant to what there asking bc it wanted to know what each person can have a total amount of combinations of . if it wanted all the freshman's total amount than it would of said all the the freshman's total combinations if that makes sense ? so yeah 75 total combinations
