Aylin went to the store to buy some new folders for school . She bought a total of 7 folders and spent a total of $12. She bought two different types of folders. Plain folders that cost $1 each and folders with cartoons that cost $2 each. How many did each type of folder did Aylin buy?

Answers

Answer:

2 plain folders and 7 folders with cartoons

Step-by-step explanation:

Given data

Let the number of plain folders be x

and the number of folders with cartoons  be y

x+y=7------------1

x+2y=12----------2

from 1

x= 7-y

put this in 2

7-y+2y=12

7+y= 12

y= 12-7

y=5

Put y=5 in 1

x+5= 7

x= 7-5

x= 2

Hence Ayin bought 2 plain folders and 7 folders with cartoons

What is the image of (8,-6) after a reflection over the line y = x?

Answers

Answer:

Step-by-step explanation:

Interchange x and y:  (-6, 8) is the image of (8, -6) after a reflection over y = x.

The image of (8,-6) after a reflection over the line y=x is (-6, 8).

The given coordinate point is (8, -6).

What is a reflection over the line y=x?

Reflect over the y = x, when you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).

The image of (8,-6) after a reflection over the line y=x is

Reflecting in the line y = x interchanges the x and y coordinates. So, the image of (8, -6) is (-6, 8).

Therefore, the image of (8,-6) after a reflection over the line y=x is (-6, 8).

Answer:

tan•= -√13/4

Step-by-step explanation:

sin2•+ cos2• = 1

sin• = √1-cos2•

sin•= √1-(-4/7)2

sin•= √1-16/49

sin•= √ 49-16/49

sin•= √ 13/ 49
