To solve the function in terms of x:

find the power of the subscripts of the log

cross multiply the expression

Therefore the correct answer of a = 6x
The answer is c. Because 4.5 * 2 is 9 then you add 0.5 so the answer is 9.5
Let t = the number of days the mouse travels
Let D = the distance that the mouse traveled
The mouse travels at a rate of 1.5 miles per day, so R = 1.5 mi/day
The equation is:
Distance (D) = Rate (R) x Time (t)
SO:
Distance (D) = 1.5 mi./day X Time (t)
