A) (4, 3) and \[(4,-3)\]
B) \[(4,-3)\]and\[(-4,-3)\]
C) \[(-4,3)\]and (4, 3)
D) (4, 3) and (3, 4)
Correct Answer: A
Solution :
Given, \[{{x}^{2}}+{{y}^{2}}=25\] ...(i) and \[{{x}^{2}}+{{y}^{2}}-8x+7=0\] ...(ii) From Eqs. (i) and (ii), \[25-8x+7=0\] \[\Rightarrow \] \[8x=32\] \[\Rightarrow \] \[x=4\]and\[y=\pm 3\] Hence, intersection points are (4,3) and\[(4,-3)\].You need to login to perform this action.
