Simplify 2/√5

1 answer:

4 0

The answer would be 2√5/5

As a rule, you cannot have any radical as a denominator. That's why you gotta multiply √5 with √5 which would be √25. The square root of this is 5, and now you have disposed of the radical! Hurray. However, keep in mind, that when you multiply √5, you also multiply it to the numerator. So, yeah, after this, you get the answer.

Hopefully, my explanation makes sense. :)

Solve for x and graph the solution on the number line 15 > 2x – 9 > -23

Monica [59]

The answer is 12>x>-7

Step-by-step explanation:

it's first divided into 2 parts

1 . 15 > 2x - 9

2. 2x - 9 > -23

Then solve them individually.

let's do it,

First half

15 > 2x - 9

15+9 > 2x

24 > 2x

24/2 > x

12>x

Second half

2x-9>-23

2x>-23+9

2x>-14

x>-14/2

x>-7

Joining of the two halves

We have :

12>x>-7

Answer:

8. (0,-2)

9. (-2,1)

Step-by-step explanation:

Lucy's house is at (1,1)

Down means in the y coordinate , left means negative x

Down 3 means subtract 3 from y

left 1 means subtract 3 from x

(1-1, 1-3)

(0,-2)

9. Lucy is at (1,1)

3 units to the left

Quadrilateral army is rotated 90° about the origin

nevsk [136]

Sorry I am late but the I think it is this, I don’t know the answer but here is what I know. answer is: Imagine a rectangle that has one vertex at the origin and the opposite vertex is A. Now that you can see the image of A(3,4) under the rotation is A’(-4,3). It is easier to rotate the points that lie on the axes, and these help us find the image of A.
POINT: (3,0) (0,4) (3,4)
IMAGE (3,0) (-4,0) (-4,3)
