Complete the square fr x and y's sepreatly to get into form
(x-h)²+(y-k)²=r²
the center is (h,k) and radius is r
so
group x's and y's seperatly
(4x²-10x)+(4y²+24y)+133/4=0
undistribute leading confident from each
4(x²-2.5x)+4(y²+6y)+133/4=0
take 1/2 of each linear confident and square it and add negative and positive inside the parenthasees
-2.5/2=-1.25 (-1.25)²=1.5625
6/2=3, 3²=9
4(x²-2.5x+1.5625-1.5625)+4(y²+6y+9-9)+133/4=0
factor perfect squares
4((x-1.25)²-1.5625)+4((y+3)²-9)+133/4=0
expand
4(x-1.25)²-6.25+4(y+3)²-36+133/4=0
4(x-1.25)²+4(y+3)²-9=0
add 9 to both sides
4(x-1.25)²+4(y+3)²=9
divide both sides by 4
(x-1.25)²+(y+3)²=9/4
(x-1.25)²+(y+3)²=(3/2)²
the center is (1.25,-3) and the radius is 1.5
Answer:
-7g+13
Step-by-step explanation:
b) because combining like terms results in:
g-8g=7g
and
15-2= 13
Answer:
7344
Step-by-step explanation:
Answer:
The choice 210
Step-by-step explanation:
![3{[3(9 - 2)] +[7(8 - 1)] }\\ 3[3(7) + 7(7)] \\ 3[21 + 49] \\ 3[70] \\ = 210](https://tex.z-dn.net/?f=3%7B%5B3%289%20-%202%29%5D%20%2B%5B7%288%20-%201%29%5D%20%7D%5C%5C%203%5B3%287%29%20%2B%207%287%29%5D%20%5C%5C%203%5B21%20%2B%2049%5D%20%5C%5C%203%5B70%5D%20%5C%5C%20%20%3D%20210)

When a fraction corresponds to a repeating decimal, it's denominator is 9 or 99.
For example, 4/11 = 36/99 = 0.36 with bar notation over 36.
Example #2: 2/3 = 6/9 = 0.666....
or also written as 0.6 with bar notation over 6.
You know a fraction responds to a terminating decimal because it can be simplified to a terminating decimal.
Example: 2/4 = 0.5
