यदि वृत्त `x^2+y^2+2ax+cy+a=0` तथा `x^2+y^2-3ax+dy-1=0` दो भिन्न बिन्दुओं P तथा Q पर प्रतिच्छेद करते है , तो रेखा `5x+by-a=0` बिन्दुओं P तथा Q से होकर जाती है : ।

If the circles x^2 + y^2 + 2ax + cy+ a = 0 and x^2 + y^2 - 3ax + dy - 1 = 0 intersect in two distinct points P and Q, then the line 5x + by - a = 0 passes through P and Q for :

If the circles : x^2+ y^2+2ax + cy +a=0 and x^2+ y^2-3ax+dy -1=0 intersect in two distinct points P and Q, then the line 5x + by- a = 0 passes through P and Q for:

If ax^2+bxy+cy^2 =0 , find x:y.

In the figure, two circles with centres P and Q touch externally at R. Tangents AT and BT meet the common tangent TR at T. If AP = 6cm and PT = 10 cm, then BT =? दी गयी आकृति में, दो वृत्त जिनके केंद्र P तथा Q हैं, वे एक-दूसरे को बाहर से R पर स्पर्श करते हैं | स्पर्श रेखाएँ AT तथा BT उभयनिष्ठ स्पर्श रेखा TR से T पर मिलती हैं | यदि AP= 6 सेमी तथा PT = 10 सेमी है, तो BT =?

If the circles x^2 + y^2 + 2ax + cy + a =0 and x^2 + y^2 - 3ax + dy - 1 = 0 intersect in two distinct points P and Q then the line 5x + by - a = 0 passes through P and Q for

In a triangle ABC, AB = 12, BC =18 and AC = 15. The medians AX and BY intersect sides BC and AC at X and Y respectively. If AX and BX intersect each other at O, then what is the value of OX? एक त्रिभुज ABC में, AB = 12, BC =18 तथा AC = 15 है। मध्य रेखा AX तथा BY, भुजा BC तथा AC को क्रमशः X तथा Y पर प्रतिच्छेद करती है। यदि AX तथा BY, O पर प्रतिच्छेदन करते हैं, तो OX का मान क्या है?

If the circles x^2+y^2+2ax+cy+a=0 and x^2+y^2-3ax+dy-1=0 intersect in two distinct points P and Q then show that the line 5x+6y-a=0 passes through P and Q for no value of a.

If the circles x^2+y^2+2ax+cy+a=0 and x^2+y^2-3ax+dy-1=0 intersect in two distinct points P and Q then show that the line 5x+6y-a=0 passes through P and Q for no value of a.

If the circles x ^(2) +y^(2) +2ax+cy+a=0 and x ^(2) +y^(2) -3ax+dy-1=0 intersect in two distinic points P and Q, then the line 5x+by-a=0 passes through P and Q for-

Q57) If the circle x^2+y^2+2ax+cy+a=0 and x^2+y^2-3ax+dy-1=0 intersect at two distinct points Pand Q, then the line 5x+by-a=0 will pass through P and Q for A. No values of a B. Exactly one value of a C. Exactly two values of a D. Infinitely many value of a
