Responses
A. A number line is shown ranging from negative 10 to 10 with numbers listed in unit increments. An open point is plotted on the number line between 3 and 4. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 10.

In option C, an open point is plotted on the number line between 3 and 4, just after 3. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 10. This represents all the values of x that satisfy the inequality.
The inequality we have is 9.5x - 1.25 < 32.
To solve it, we can start by isolating the variable x. Adding 1.25 to both sides of the inequality, we get:
9.5x < 33.25.
Next, we divide both sides of the inequality by 9.5 to solve for x:
x < 33.25/9.5.
Simplifying, we have:
x < 3.5.
Now, let's consider the given options again:
A. An open point is plotted on the number line between 3 and 4. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 10.
B. A closed point is plotted on the number line between 3 and 4. A leftward arrow is marked on the number line that originates at the closed point and goes beyond negative 10.
C. An open point is plotted on the number line between 3 and 4, just after the 3. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 10.
D. A closed point is plotted on the number line between 4 and 5, just before 5. A leftward arrow is marked on the number line that originates at the closed point and goes beyond negative 10.
Based on our solution x < 3.5, option C is the correct graph.
Let's recheck the options and solve the inequality again.
The inequality is 9.5x - 1.25 < 32.
To solve it, we can start by isolating the variable x. Adding 1.25 to both sides of the inequality, we get:
9.5x < 33.25.
Next, divide both sides of the inequality by 9.5:
x < 33.25/9.5.
Simplifying, we have:
x < 3.5.
Now let's consider the given options:
A. A number line is shown ranging from negative 10 to 10 with numbers listed in unit increments. An open point is plotted on the number line between 3 and 4. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 10.
B. A number line is shown ranging from negative 10 to 10 with numbers listed in unit increments. A closed point is plotted on the number line between 3 and 4. A leftward arrow is marked on the number line that originates at the closed point and goes beyond negative 10.
C. A number line is shown ranging from negative 10 to 10 with numbers listed in unit increments. An open point is plotted on the number line between 3 and 4, just after the 3. A leftward arrow is marked on the number line that originates at the open point and goes beyond negative 10.
D. A number line is shown ranging from negative 10 to 10 with numbers listed in unit increments. A closed point is plotted on the number line between 4 and 5, just before 5. A leftward arrow is marked on the number line that originates at the closed point and goes beyond negative 10.
Based on our solution x < 3.5, the correct graph that shows the solution is option A.
In option A, an open point is plotted on the number line between 3 and 4, and a leftward arrow originates at the open point and goes beyond negative 10. This represents all the values of x that satisfy the inequality.
