Answer:
She spends 2 hours driving.
Step-by-step explanation:
The formula given is:
In which d is the distance traveled, r is the rate of speed, and t is the amount of time spent traveling.
Grace drives her truck a distance of 80 miles at a steady speed of 50 miles per hour.
This means that 
To the nearest hour, how many hours does she spend driving?
We have to find t. So
Rounding to the nearest hour
She spends 2 hours driving.
One minute is 60 seconds so 2 minutes are 120 seconds :)))
Answer:
tbh I think its the middle one
Step-by-step explanation:
Answer:
(-6,3) and (-4,-5) are the solutions to the system
Step-by-step explanation:
The solution to a system of equations are the point(s) where the graphes intersect. On the graph is a linear function and an exponential. Because of the curve in the exponential, the graph has two solutions at (-6,3) and (-4,-5).
Answer:
Step-by-step explanation:
We start with the equation:
We want to find the value of:
We can start with our previous equation and multiply both sides by a:
Now we can rewrite our initial expression as:
Replacing that in the right side, we get:
Now again, let's multiply both sides by a
So we can conclude that:
