dollar annual fee and the other which charges 333 dollars per book he borrows.
Here's a graph that shows a system of equations for this scenario where xxx is the number of books Aaden borrows and yyy is the total cost of the subscription.

Answer:

See explanation.

Step-by-step explanation:

Hi, you provided a very limited information to enable us answer your question.

From the given information, this is what we can help you with.

The total annual cost is

y = 3x + 96

because there is a fixed cost of $96 and there is an additional charge of $3 per books borrowed.

If Aaden borrow x books, the total cost will be

y = 3x + 96

Nitella [24]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y\geq -x^{2}-1

The solution of the inequality is the shaded area above the solid line of the equation of the  parabola y= -x^{2}-1

The vertex of the parabola is the point (0,-1)

The parabola open downward (vertex is a maximum)

All of the following expressions are equal to N except _____. |−N| −(−N) |N| −N
Maksim231197 [3]

Answer:

D. -N

Step-by-step explanation:

Our four given expressions are:

A. |-N|

B. -(-N)

C. |N|

D. -N

The | | symbols represent absolute value, which is the distance from the value within the two lines and 0; essentially since it measures distance, absolute value always outputs a positive value.

In choice A, we have |-N|, which means the distance between -N and 0. Well, the distance will simply be N, which is equal to N. Eliminate A.

In choice B, we have -(-N). Double negatives signal that they will cancel out to become positive, so -(-N) = N. Eliminate B.

In choice C, we have |N|, which means the distance between N and 0. This is clearly just N, so eliminate C.

In choice D, we have -N, which denotes "negative N". Clearly, "negative N" (-N) is not the same as "positive N" (N), so D is the answer.

Samuel was riding in the back seat of the station wagon on the way home after a long and tiring day at the
ki77a [65]

Answer: One fourth of the entire trip.

Step-by-step explanation:

The initial distance is D.

" He fell asleep halfway home."

Then he fells asleep when the distance between his actual position and his house was half of D, or:

D/2.

"He didn't wake up until he still had half as far to go as he had already

gone while asleep."

So he wakes up when his actual position is a fourth of the initial distance:

(D/2)/2 = D/4.

Then if the entire trip has a distance D, and he was sleeping between:

D/2 - D/4 = 2D/4 - D/4 = D/4.

in a trip of a distance D, he was asleep a distance of D/4.

Then, returning to the question:

How much of the entire trip home was Samuel asleep?

This is equal to the quotient between the distance that he travels asleep and the total distance:

r = (D/4)/D = 1/4.

Then he was asleep in 1/4 of the entire trip.
