Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

(x,y)\to (-x,-y)

We know that,

1260^\circ=1080^\circ+180^\circ

1260^\circ=3\times 360^\circ+180^\circ

After 3\times 360^\circ rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

(7,12)\to (-7,-12)

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

sattari [20]

Answer:

x + y = 64

x = y + 14

Step-by-step explanation:

Given:

Total number of student = 64

x = number of students in filmmaking club

y = number of students in yearbook club.

Computation:

So,

x + y = 64

And,

x = y + 14

So

Number of students in yearbook club = 25

Number of students in filmmaking club = 39

Aicel,Bessy,Cynthia went to the farm to pick guavas. They picked 120 guavas in all. Aicel picked twice as many as Bessy did and
LenaWriter [7]

Answer:

Cynthia = 12 guavas

Bessy = 36 guavas

Aicel = 72 guavas

Step-by-step explanation:

Total guavas = 120

Let

Cynthia = x

Bessy = 3x

Aicel = 2(3x)

= 6x

x + 3x + 6x = 120

10x = 120

x = 120/10

x = 12

Cynthia = x

= 12 guavas

Bessy = 3x

= 3(12)

= 36 guavas

Aicel = 6x

= 6 × 12

= 72 guavas

Total = 74 + 36 + 12

= 120 guavas
