The sum of 2, 6, and a number amounts to 15. Find the number.

1 answer:

8 0

Given the numbers, let’s set up an equation:

2 + 6 + n = 15

We can solve this using steps:

1. Simplify

8 + n = 15

2. Subtract 8 from both sides

(8 - 8) + n = 15 - 8

3. Simplify

n = 7

Let’s plug in 7 to see if it makes sense:

2 + 6 + 7 = 15

Because this equation is true, we have found our number.

Our unknown number is 7.

Rectangle KLMN is graphed on the coordinate plane below. On a coordinate plane, rectangle K L M N has points (2, negative 2), (5

gladu [14]

Answer: The correct option is (A) (2, -2).

Step-by-step explanation: Given that rectangle with vertices at K, L, M and N is graphed on the coordinate plane as shown in the figure.The figure is rotated 360° counterclockwise using the origin as the center of rotation.

We are to find the location of the image of point K after the rotation.

We know that

a rotation of 360° in counterclockwise direction about the origin map a point to itself. That is, the co-ordinates of the image point will be same as the original one.

From the figure, we see that the co-ordinates of point K are (2, -2).

Therefore, after rotation of 360° counterclockwise using the origin as the center of rotation,

the co-ordinates of the image of point K will also be (2, -2).

Thus, the location of the image of point K is (2, -2).

Option (A) is CORRECT.
