Pleaee i have tirwe but coupd fins rhe ans

Step-by-step explanation:

substitute x = 2y + 5 into the equation of the circle

(2y + 5 )² + y² = 5

4y² + 20y + 25 + y² - 5 = 0

5y² + 20y + 20 = 0 ( divide all terms by 5 )

y² + 4y + 4 = 0

Use the discriminant to determine the nature of the roots

with a = 1, b = 4 and c = 4

b² - 4ac = 4² - (4 × 1 × 4 ) = 16 - 16 = 0

Since b² - 4ac = 0 there are 2 equal solutions, at

y² + 4y + 4 = 0

(y + 2 )² = 0 ⇒ y =  - 2 and x = (2 × - 2 ) + 5 = 1

Hence x = 2y + 5 is a tangent to the circle with point of contact (1, - 2)

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
