Answer:
A. Exactly one solution
Step-by-step explanation:
Solve the system of equations.
y = x + 1
y = 2x - 5
Substitute one equation into the other.
y = 2x - 5
x + 1 = 2x - 5
Subtract 2x from both sides.
-x + 1 = -5
Subtract 1 from both sides.
-x = -6
Multiply both sides by -1.
x = 6
Put it back into the other equation.
y = x + 1
y = 6 + 1
Add.
y = 7
The solution is (6, 7). Since the equations aren't equal, there are not infinitely many solutions, but since there is a solution found, we can determine that there is exactly one solution.
Answer:
0-27
Step-by-step explanation:
The range of a function is representative of the values on the y-axis. In this case, the graph will contain distance on the y-axis at is the dependent variable, while the independent variable is time.
We know that the minimum value of the distance will be 0, given that there can be no negative distance. Moreover, the maximum value is 26.2 miles, since the marathon will then be over. Therefore, a good range for the situation will be 0-27 miles.
I hope this helps. I am sorry if you get this wrong.
