Answer: v=0
Step-by-step explanation:
Because....
Step 1: Simplify both sides of the equation.
−v+ 1= 8v + 1
Step 2: Subtract 8v from both sides.
−v+1 − 8v = 8v+1 − 8v
−9v + 1 = 1
Step 3: Subtract 1 from both sides.
−9v + 1 −1 = 1−1
−9v=0
Step 4: Divide both sides by -9.
v=0
Therefor, the answer is v = 0

Answer:
The quadratic equation in terms of v is v² + 2 v + 180 = 0
Step-by-step explanation:
Given as :
The distance between house to the school = d = 6 km
The uniform speed = v km/h
So, Time =
or, t =
Or, t =
<u>Now, Again</u>
The speed is increase by 2 km/h
i.e speed = (v + 2) km/h
So, Time taken = t' = (t - )hours
i.e t' = (t - )hours
Now, Time =
So, (t - ) =
Or, (t - ) =
Or , -
=
Or , =
Or, (90 - v) × (v + 2) = 6 × 15 v
Or, 90 v - 180 - v² - 2 v = 90 v
Or, v² + 2 v + 180 = 90 v - 90 v
Or, v² + 2 v + 180 = 0
So, The quadratic equation in terms of v
v² + 2 v + 180 = 0
Hence The quadratic equation in terms of v is v² + 2 v + 180 = 0 Answer
