Place Brunhilda at (0,0) which is the location of the intersection of the x and y axis. I'm going to label this point A.

Move 3 units to the right to arrive at point B = (3,0). Then move 2 units up to arrive at point C = (3,2). The next step is to walk 5 units to the left and you get to point D = (-2,2). Finally, we move 2 units south to get to the point E = (-2,0)

When we talk about displacement, we only care about starting and ending points. The stuff in between doesn't matter. We start at (0,0) and end at (-2,0). So the displacement is 2 units to the right or "2 meters west"

Answer: Choice C) 2 m west

Check out the attached image to see a visual of what is going on.

Edit: I mistakenly thought she started at point A. instead she starts at point B. So the answer is actually 5 meters west.

2.4x-9 < 1.8x+6 solve the inequality
nasty-shy [4]

Answer:

x<25

Step-by-step explanation:

Let's solve your inequality step-by-step.

2.4x−9<1.8x+6

Step 1: Subtract 1.8x from both sides.

2.4x−9−1.8x<1.8x+6−1.8x

0.6x−9<6

Step 2: Add 9 to both sides.

0.6x−9+9<6+9

0.6x<15

Step 3: Divide both sides by 0.6

0.6x/0.6 < 15/0.6

x<25

An electrician needs to run a cable from the top of a 40​-foot tower to a transmitter box located 30 feet away from the base of
grin007 [14]
The cable should be 50 feet.

If you draw the picture, you will see that you have a right triangle.

Let's just use the Pythagorean Theorem to find the hypotenuse (or cable).

30^2 + 40^2 = c^2
2500 = c^2
50 = c

Two friends Ana and Juan are buying books by joining the History Book
Travka [436]

Answer:

Ana  spent $17  per book on average.

Juan  spent $14.78  per book on average.

y = $15 + 17x--------- equation 1

y= $10 + 14.78 x------------- equation 2

Step-by-step explanation:

Ana has to pay a yearly fee of $15 to join.

She spends a total of $525 for 30 books.

The amount spent on books = Total amount - yearly fee

                                                 = $525- $15= $510

Price per book on the average = $510/30= $ 17

Ana  spent $17  per book on average.

Juan has to pay a yearly fee of $10 to join.

He spends a total of $350 for 23 books.

The amount spent on books = Total amount - yearly fee

                                                 = $350- $10= $340

Price per book on the average = $340/23= $ 14.78≅ $15

Juan  spent $14.78  per book on average.

The function can be established if y gives the total cost and x gives the number of books

y = $15 + 17x--------- equation 1

y= $10 + 14.78 x------------- equation 2

Juan has a better deal because the yearly fee is less also the price per book is less.
