Options:
(12,0) (0,12) (3,-1) (0,-4/3)
Answer:
(12,0)
, (3,-1) and (0,-4/3)
Step-by-step explanation:
Given
Required
Which option is true?
A coordinate point is of the form;
So, we have to substitute the x and y values in the given equation.
A. For (12,0)
and
becomes
<em>This is true</em>
B. For (0,12)
and
becomes
<em>This is false</em>
C. For (3,-1)
and
becomes
<em></em>
<em></em>
<em>This is true</em>
D. For (0,-4/3)
and
becomes
<em></em>
<em>This is true</em>
<em></em>
<em>Hence, (12,0)
, (3,-1) and (0,-4/3) are true values of the equation</em>
<span>Given the two end of the diameter of the circle, we are able to compute the center of the circle as 0.5*[(-1,3)+(7,-7)]=(3,-2). The radius of the circle is 0.5*sqrt[(-1-7)^2+(3+7)^2]=sqrt(41). Therefore the equation of the circle is (x-3)^2+(y+2)^2=41.</span>
You can either make -5 or -7 positive numbers meaning either make it (5)(-7) or (-5)(7). Two negative numbers multiplied together make a positive number.
Hope this helps!
