Answer:

f(x) = 2

Trial and error method is different and it is used here.

I have taken x as 1 which does not give right answer and then moved on to 2 which does equate both sided.

Step-by-step explanation:

2x + 5 = 9

f(x) = 1

2 X 1 + 5 = 7
x=/=1

f(x) = 2

2 X 2 + 5 = 9
x = 2

Let us first find the total time taken to cover the distance of 125 m. Using the second equation of motion, we get: ⇒ s = ut + 0.5 at² ⇒ 125 = 0(t) + 0.5 ( 10 ) (t)² ⇒ 125 = 5t² ⇒ t² = 125/5 ⇒ t² = 25 ⇒ t = √25 = 5 seconds. Hence the time taken to cover the distance of 125 m is 5 seconds. Now 1/4th of 125 m is given as: \implies \dfrac{1}{4} \times 125 = 31.25 \:\:m⟹ 4 1 ...
