The negative x- and y-axes are tangents to a circle, C.
(i) How are the coordinates of the
centre of C related?
The line l is the tangent to C at the point
P(-8, -9) on the circle. The centre of
C lies above and to the right of P.
(ii) Find the equation of C.
(iii) Find the equation of l.

1 - along -x=y

Step-by-step explanation:

Use completing square and then subtract.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
