Answer:
D
Step-by-step explanation:
The answer to this problem should be the 4th one.
All real numbers can't be right as 0 obviously wont work. However, it is important to remember that sqrt of a number cant be negative, so x must either be greater than or equal to -1 and 1
What do you notice about each solution? :
Picture 1 - They never intersect/touch.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other.
What do you notice about the graphs for each set of equations? :
Picture 1 - The lines are parallel.
Picture 2 - They are intersecting.
Picture 3 - They are on top of each other. (otherwise known as coincident lines).
What do you notice about each set of equations? :
Picture 1 - They have the same slope but different y-intercepts.
Picture 2 - Both the slopes and y-intercepts are different for each equation.
Picture 3 - They have the same slope and same y-intercept.
What generalization can you make? :
Picture 1 - When equations have the same slope but different y-intercepts they will be parallel when graphed.
Picture 2 - When the equations have different slopes and different y-intercepts they will be intersecting.
Picture 3 - When the equations are the same they will be coincident lines when graphed.
Answer:
66.7
num 4
Step-by-step explanation:
The exact distance she drove was 236.39 miles
61.4 miles per hour x (times) 3.85 hours = 236.39 miles in total
