The answer to that is 62.78
The total distance is given as 18 miles
she traveled at 45 miles per hour for 20 minutes
20 minutes = 20 / 60 = 1/3 of an hour
45 miles per hour x 1/3 of an hour = 15 miles driven
18 total miles - 15 miles driven = 3 miles left
she then drove at 20 miles per hour
20 miles per hour / 60 minutes per hour = 1/3 mile per minute = 1 mile every 3 minutes
3 miles x 3 minutes = 9 minutes to drive the final 3 miles
20 minutes + 9 minutes = 29 total minutes to drive to work
she left at 7:15
7:15 + 20 minutes = 7:35 am she arrived at work
Answer:
Answer is -6
Step-by-step explanation:
We can say that f(x) = 3x - 12
According to the question we have:
f(2) = 3x - 12
This means that x = 2
To solve this we substitute 2 in place of x
12b+3=-2b-4
14b=-7
b=-1/2
Check
-2(-1/2)-4 =-3
12(-1/2)+3=-3
Answer:
The slope is 3.5
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
Observing the graph
we have the points
(0,0) and (4,14)
substitute in the formula
Simplify
