The true statement about unbalanced forces is:
**They can change both an object's speed and direction.**
Unbalanced forces cause changes in the motion of an object, which includes changes to both its speed and its direction.

The statement that best explains why the box does not move is:
**Balanced forces do not cause change in motion.**
In this scenario, if the box is not moving despite two people applying forces from opposite directions, it indicates that the forces are balanced, meaning they have the same magnitude and are acting in opposite directions, resulting in no net force acting on the box.

The unit used for measuring force is:
**newton**.
One newton (N) is defined as the amount of force required to accelerate a one-kilogram mass by one meter per second squared.

The example that shows unbalanced forces acting on an object is:
**Two people are on the same side of a large box. One person pushes the box and the other pulls the box with equal force.**
In this scenario, the forces acting on the box are not balanced because one person is pushing while the other is pulling; thus, the net force will change depending on the direction and type of force applied.

The statement that BEST describes why the refrigerator does not move is:
**The person applies too much force to the refrigerator, and now the forces on the refrigerator are balanced.**
This implies that the force she is applying is equal to the opposing forces (such as friction and weight) acting on the refrigerator, resulting in no movement.

The statement is **true**, because the lines are parallel.
To explain further:
1. The equation \( y = -x + 3 \) represents a line with a slope of -1 and a y-intercept of 3.
2. The equation \( x + y = 8 \) can be rearranged to \( y = -x + 8 \), which is a line with the same slope of -1 but a different y-intercept (8).
Since both lines have the same slope (-1) but different y-intercepts (3 and 8), they are parallel and will never intersect. Therefore, there is no solution to the system of equations.
