Answer:
(x-2)²+(y+3)²=9
Step-by-step explanation:
We know that the formula for the area of the circle is:
(x-h)²+(y-k)²=r²
-h,k being the center coordinates
-r being the radius
In this case, (2,-3) are the center coordinates and 3 the radius, so simply plug these into the equation giving us:
(x-2)²+(y+3)²=9
<u><em>Answer: =38 *The answer should be the positive.*</em></u>
Step-by-step explanation:
You had to used stands for P-parenthesis, E-exponents, M-multiply, D-divide, A-add, and S-subtract. It can also go left to right. First, calculate parenthesis. This gives us 32-8=24. Then rewrite the problem. This gives us 6*24/4+2. Multiply and divide left to right. This gives us 6*24=144/4. 144/4=36+2. This gives us the final answer is 36+2=38.
Hope this helps!
Thanks!
Have a great day!
Answer:
h = 2a/b
Step-by-step explanation:
a = 1/2 bh
2*a = 2* 1/2 bh
2a = bh
2a/b = bh/b
2a/b = h
Answer:
y = 0
Step-by-step explanation:
-2y-4=4(y-1)
First you want to distribute it
-2y - 4 = 4y - 4
Then just subtract -4y from both sides to neutralize 4y
-6y -4 = -4
then you have to add 4 to neutralize -4
-6y= 0
thus the answer is y= 0
