Answer:
Option A
Step-by-step explanation:
The standard form of an equation of a circle is represented by the formula 
. Remember that 
is the center and 
is the radius squared.
So, the equation of the circle must be 
. Complete the square to change the form of the equations listed in the options and find the one that is equal.
Let's try this with option A. Move the constants to the right side, then use the completing the square method to place the equation in standard form:
The end result matches with the equation determined before, so option A is the answer.
Answer:
No
Step-by-step explanation:
Apply Pythagorean theorem: a2 + b2 = c2
The sum of the squares of the legs of a right triangle equals the square of its hypotenuse.
I hope this answer will help you. Have a nice day !
First off we want to combine "like-terms"
1. Subtract 6x , so it will look like this: 2x-6x+12=-12
2. Subtract the -12 from the first side so it looks like 2x-6x=-12-12
3. Combine like terms. So: -3x=-24 . The negatives will cancel out when dividing 24/3.
The final answer is 8 after dividing. Hope this helped!
Answer:
The constant of proportionality (k) is 1/5.
Step-by-step explanation:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
Hope this helps and I hope u have an Amazing day!!
