Answer:

C. f(x) = x - 7 all over 4

Step-by-step explanation:

NB: Let f(x) = y

Exchange X and Y

Make y the subject

f(x) = 4x + 7

y = 4x + 7

x = 4y + 7

x - 7 = 4y

x - 7 all over 4 = 4 ÷ 4

y = x - 7 all over 4

OB is the perpendicular bisector of AD. AO = 2x + 5 and OD = 3x _ 5. Solve for x
Sphinxa [80]
As OB is the perpendicular bisector of AD. So AO = OD
Hence 2x + 5 = 3x – 5
3x – 2x = 5 + 5
