Rearrange x²+y²-4x+6y=-11 I'll tell you an easy way. take the coefficient of x and divide it by -2 and the coefficient of y and divide it by -2 so -4 ÷-2 = 2 6÷-2= -3 (2,-3) is the center of the circle to know the radius √2² + -3² + -11 =√2 The Radius equals √2
<u>Answer:</u>
The correct answer option is C. 13.6 units.
<u>Step-by-step explanation:</u>
Line segment AB was dilated to create the line segment A'B' using the dilation rule
.
We are to find the value of
which is the distance between the twp points A and A'.
For this, we will divide the distance of A'Q by the dilation factor and then subtract the given length.

x =
= 13.6 units
For this problem, we just have to use the values we're given to calculate the approximate value of pi.
The formula presented is

When you have a negative exponent, we can use the following property

Using this property, our problem turns out to be

Now, we just need to plug the given values on this equation

The approximated value for pi is 3.142.
Answer:
See explanation
Step-by-step explanation:
We want to find the value of k in

We subtract 3 from both sides;

Simplify on the right;

Square both sides;


If your equation in actually

Square both sides:



Answer: The answer is: One solution.
Infinitely Many Solutions - The unknown x assumes infinite numerical values. Thus, the equation has infinite solutions.
Ex: x+2=x+2
No solution: It has no solution.
Example:
0x = 4 → Unable to divide 4 by 0.
Step-by-step explanation: These are equations that admit at least one solution.
3x+9+4x+x=
3x+4x+x=9
8x=9
x=<u>9</u>
