Q22
The graph of the equations 25x + 75y = 225 and x = 9 meet at the point:
A.
(0, 9)
B.
(9, 0)
AnswerC.
(3, 0)
D.
(0, 3)
Answer: Option B
Solution
Answer: Option B
Solution:
25x + 75y = 225 . . . . . . (i)x = 9 . . . . . . (ii)
For meeting point, solving the equation (i) & (ii)
⇒ 25 × 9 + 75y = 225
⇒ 75y = 225 - 225
⇒ y = 0
∴ Meeting point = (9, 0)
