Answer:
2j+57
Step-by-step explanation:
Two times a umber j is expressed as 2j
if Fifty-seven is more than two times j", this means we will have to add 57 to 2j as shown;
f(j) = 2j + 57
Hence the statement written as a function is expressed as 2j+57

Answer:
for every extra mile an employee drives, the driving time increases by 1.3 minutes
Step-by-step explanation:
Step 1: The given regression equation y = 1.3x + 6.8, where "x" is the number of miles and "y" is the time taken.
Step 2: Here the constant 6.8 remains the same. For each extra mile, the time increases by 1.3
For example, let's take x = 2 miles, the time taken y = 1.3(2) + 6.8
= 2.6 + 6.8
y = 9.4
Let's take x = 3, the time taken y = 1.3(3) + 6.8
= 3.9 + 6.8
y =10.7
You can see the difference in the timing by 1.3.
Therefore, for each extra mile, the time is increases by 1.3 minutes.
Thank you.
