Answer:
0
Step-by-step explanation:
this is the only answer because if you subtract 2a from both sides you are left with b= since there is nothing there, that makes it 0. There is no way to solve this without b=0. (i think its a TRICK question)
To take a square root of a decimal that can be taken the square root fully, in other words not an irrational number, one can write the decimal as a fraction then take the square root of both the top and bottom values.
For example : sq. root of 0.5
Sq root (1/2) = sq. root of 1/sq root of 2
1/ sq root of 2 or sq. root or 2/2.
Answer:
Solution given:
the equation of a circle is:
x²+y²-6x-2y+4=0
x²-2*x*3+3²+y²-2y+1²-1²+4=0
(x-3)²+(y-1)²=9+1-4
(x-3)²+(y-1)²=6
comparing above equation with
(a-h)²+(y-k)²=r²
we get
centre (h,k)=(3,1)
radius=√6
option first
<u>(3,1), r = </u><u>√</u><u>6</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>
Answer: Using the slope-intercept form, the y-intercept is 0 .
