Answer:

X=SMALL BOX.

Y=LARGE BOX

THEREFORE,X+Y=21

X=21-Y

THEREFORE,25(21-Y)+70Y=1110 POUNDS

525-25Y+70Y=1110

525+45Y=1110

45Y=1110-525

45Y=585

Y=585/45

Y=13 .

Therefore,13 large box and8 small box..

Airida [17]

$r=-8\sec\theta=-\dfrac8{\cos\theta}\implies r\cos\theta=-8$

Converting from rectangular coordinates to polar coordinates involves setting $(x,y)=(r\cos\theta,r\sin\theta)$ . Since the left hand side matches $x$ perfectly, the equation's rectangular coordinate form is $x=-8$ .
