The vertex is on the axis of symmetry, so the axis of symmetry is x = 3. Find any two x-intercepts that have the equivalent distance from the axis of symmetry. Use those x-intercepts to write factors of the function by subtracting their values from x. For example, 2 and 4 are each 1 unit from x = 3, so f(x) = (x – 2)(x – 4) is a possible function.
Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
Answer:
17 km per hour
Step-by-step explanation:
60/4 = 15
68/4 = 17
This is a bit of a guess, but I think probably a) +4 and also a) -215
Answer:
Step-by-step explanation:
Add 
to both sides:
Subtract 2 from both sides:
Divide both side by 2:
