To analyze the sum \( p + (-q) \), we can rewrite it as \( p - q \). Since both \( p \) and \( q \) are positive numbers, the result will depend on their relative sizes.

  1. If \( p > q \), then \( p - q \) is positive and represents the distance from \( q \) moving in the positive direction.
  2. If \( p < q \), then \( p - q \) is negative and represents the distance from \( p \) moving in the negative direction.
  3. If \( p = q \), then \( p - q = 0\).

Now, out of the given options, the correct interpretation of the sum \( p + (-q) \) or \( p - q \) can be summarized as follows:

  • If \( p > q \): It is \( p - q \), and you can visualize this as starting at \( q \) and moving a distance of \( p \) to the right (positive direction).

  • If \( p < q \): The absolute value \( |p| \) indicates how far you are from \( q \) in the negative direction.

The best choice to express this generally, without assuming more about the relationship between \( p \) and \( q \), is:

The sum \( p + (-q) \) is the number located a distance \( |q| \) from \( p \) in the negative direction.

When \( p < q\), you're moving left and vice versa, confirming that \( p + (-q) \) could represent different positions based on the values of \( p \) and \( q \).

Question Use properties of operations to add (−3) and (−17) .(1 point) Responses −14 negative 14 20 20 −20 negative 20 14

To add \((-3)\) and \((-17)\), you can use the following steps:

\[ (-3) + (-17) = -3 - 17 \]

When adding two negative numbers, you add their absolute values and keep the negative sign:

\[ 3 + 17 = 20 \]

Thus,

\[ (-3) + (-17) = -20 \]

So, the correct answer is:

−20

Add (4) and (−15).(1 point) Responses −19 negative 19 19 19 −11 negative 11 11

To add \(4\) and \(-15\), you can set it up as follows:

\[ 4 + (-15) = 4 - 15 \]

When you subtract a positive number from a smaller positive number, you get a negative result:

\[ 4 - 15 = -11 \]

So, the correct answer is:

−11

Add (−18) and (5) .(1 point) Responses −13 negative 13 23 23 −23 negative 23 13

To add \((-18)\) and \(5\), you can set it up as follows:

\[ -18 + 5 \]

This can be interpreted as starting at \(-18\) and moving \(5\) units to the right (towards the positive direction).

Calculating that:

\[ -18 + 5 = -13 \]

So, the correct answer is:

−13

Which number line shows the correct way to find the sum p+q if p is positive and q is negative?(1 point) Responses Image with alt text: A number line ranging from 0 in unit increments shows an arrow, labeled absolute value of q, starting at point p and ending 4 units to the right. Image with alt text: A number line is shown with arrows at both ends, and hash marks at unit intervals. Point p is marked on the seventh interval from the left. Zero is marked 2 intervals to the right of p. A leftward curved arrow, labeled absolute value of q, points from p to the second interval from the left. Image with alt text: A number line is shown with arrows at both ends, and hash marks at unit intervals. The second point from the left is labeled p. Zero is marked at 6 intervals to the right of point p. A rightward curved arrow, labeled absolute value of q, starts at p and ends 4 intervals to the right of p.

To find the sum \( p + q \) where \( p \) is a positive number and \( q \) is a negative number, you need to start at the position of \( p \) on the number line and then move left by the absolute value of \( q \).

Since \( q \) is negative, the arrow should point to the left from \( p \), indicating a decrease in value.

Given that understanding, the correct number line would be the one that shows:

  • Point \( p \) on the number line, representing the positive value.
  • An arrow pointing leftward from \( p \), indicating that you are subtracting the absolute value of \( q \).

From your descriptions, the correct option would be:

The number line where point p is marked on the seventh interval from the left and shows a leftward curved arrow labeled absolute value of q pointing from p to the second interval from the left.

This correctly illustrates moving from the positive position \( p \) left by the magnitude of \( q \) to find the sum \( p + q \).
