Is 12.89 irrational
STatiana [176]

No.  It's the ratio of  1,289  to  100 .

Also, it can be written as a fraction with whole numbers
on top and bottom, like this:    1289 / 100 .

Also, it can be written down on paper completely, using
digits and a decimal point or fraction bar.  (You did that.)

Any one of these three facts makes it a rational number.

Whats the center and the radius of the circle(x+4)²+(y+6)²=64
inessss [21]

Answer:

The center is (-4,-6) and the radius is 8

Step-by-step explanation:

(x+4)²+(y+6)²=64

The equation of a circle can be written in the form

(x-h)²+(y-k)²=r^2

Where (h,k) is the center and r is the radius

Rewriting the equation

(x - -4)²+(y- -6)²=8^2

The center is (-4,-6) and the radius is 8

3(2x + 1 ) = 2(x + 1) + 1
SpyIntel [72]

3(2x+1)=2(x+1)+1

Step 1:Simplify both sides of the equation

(3)(2x)+(3)(1)=(2)(x)+(2)(1)+ -(distribute)

6x+3=2x+2+1

6x+3=(2x)+(2+1) -(Combine Like Terms)

6x+3=2x+3

Step 2: Subtract 2x from both sides

6x+3-2x=2x+3-2x

4x+3-3=3-3

4x÷4=0÷4

x=0
