Each day that a library book is kept past its due date, a $0.30 fee is charged at midnight. Which ordered pair is a viable solution if x represents the number of days that a library book is late and y represents the total fee?Answers:
(–3, –0.90)
(–2.5, –0.75)
(4.5, 1.35)
(8, 2.40)

Answers

Answer 1
Answer: Let's say the number of days library book is late is X, and the total fee is Y.

Liability charges $0.30 dollars as a fee for being 1 day late,

For being 1 day late, fee charge is: 1* $0.30
So, for X days the charge would be: X*$0.30.

Total charge for being X days late is Y, Which means: Y= 0.30 * X.

Now We would have to check all the viable solutions in the answer to see if they satisfy the equation Y= 0.30 * X

Optionone(-3, -0.9) and two (-2.5, -0.75) Would not be a viable solutionbecause the value of number of days can not be negative and in optionone and two, value of days -3 and -2.5 is negative.

Optionthree(4.5, 1.35) can not be correct because library charges fee for afull day so the number for days would be a whole number. Library wouldnot charge for 4.5 days, they would either charge of 4 days or 5 daysbecause 4.5 is not an whole number.


Option four(8, 2.40) is the correct answer because it satisfies our equation;

Y= 0.30 * X

2.40= 0.30 * 8

2.40 = 2.40.


Fourth option (8, 2.40) is the only viable solution to this question.

Triangle ABC is translated to image A′B′C′. In this translation, A(5, 1) maps to A′(6, –2). The coordinates of B′ are (–1, 0). What are the coordinates of B? B( , )

Answers

Answer:

B' (-2, 3)

Step-by-step explanation:

A(5, 1)  to A'(6, -2)

A(6-5, -2-1)

A translation is 1, -3

consider the same translation of B'

therefore, the coordinates of B' is (-2, 3)

Mr. Hann is trying to decide how many new copies of a book to order for his students. Each book weighs 6 ounces.Which ordered pair is a viable solution if x represents the number of books he orders and y represents the total weight of the books, in ounces?

Answers

The answer that only made sense to me is (0,0)
x + 6y x being the number of books he orders, considering you have no idea how many books he need this remains x. the information you do know is every book weighs 6oz. this is your y value.
