Numberlines: 1st numberline shows -2 going to the left and is open, the 2nd numberline shows +12 going to the left
Answer choices:8x < 4x + 24, -3 ( x-12) > 0, -5 (x+5) > - 15, 1/4 (8x+16) > -4

5 answers

To match the inequalities to their graphed solutions based on the provided information about the number lines:

  1. First Number Line: This number line shows -2 going to the left, and the endpoint is open. This indicates that the inequality is of the form \( x < -2 \) or \( x > -2 \).

  2. Second Number Line: This number line shows +12 going to the left, suggesting that it is an inequality of the form \( x < 12 \).

Let's analyze the given inequalities:

  1. \( 8x < 4x + 24 \): Simplifying this, we get \( 4x < 24 \) or \( x < 6 \).
  2. \( -3(x - 12) > 0 \): Simplifying this, we find \( -3x + 36 > 0 \) or \( -3x > -36 \), which gives \( x < 12 \).
  3. \( -5(x + 5) > -15 \): Simplifying gives \( -5x - 25 > -15 \), which leads to \( -5x > 10 \) or \( x < -2 \).
  4. \( \frac{1}{4}(8x + 16) > -4 \): Solving this results in \( 2x + 4 > -4 \) which simplifies to \( 2x > -8 \) or \( x > -4 \).

Matching the inequalities:

  • The first number line (open circle at -2, going left) corresponds to \( -5(x+5) > -15 \) since it leads to \( x < -2 \).
  • The second number line (open circle at +12, going left) corresponds to \( -3(x - 12) > 0 \) as that results in \( x < 12 \).

Final Answers:

  1. First number line: -5(x + 5) > -15
  2. Second number line: -3(x - 12) > 0

Distribute to get Response area Combine like terms to get Response area Use the (choose a property) Response area to get (resulting equation) Response area Use the (choose a property) Response area to get (resulting answer) Response area

Let's break down the solution to the equation \( 2(x - 3) + 21 = -3\), filling in the necessary steps.

  1. Distribute to get:

    • Distributing \(2\) into \((x - 3)\): \[ 2 \cdot x - 2 \cdot 3 = 2x - 6 \] So, we have: \[ 2x - 6 + 21 = -3 \]
  2. Combine like terms to get:

    • Combine \(-6\) and \(21\): \[ 2x + 15 = -3 \]
  3. Use the (choose a property):

    • Use the addition property of equality to subtract \(15\) from both sides: \[ 2x + 15 - 15 = -3 - 15 \] Resulting in: \[ 2x = -18 \]
  4. Use the (choose a property):

    • Use the division property of equality to divide both sides by \(2\): \[ \frac{2x}{2} = \frac{-18}{2} \] Resulting in: \[ x = -9 \]

Summary of Steps:

  • Distribute to get: \(2x - 6 + 21 = -3\)
  • Combine like terms to get: \(2x + 15 = -3\)
  • Use the addition property of equality to get: \(2x = -18\)
  • Use the division property of equality to get: \(x = -9\)

You can fill in each response area with the corresponding explanation above.

Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can also be moved by dragging with a mouse. ax−44<15 ax+15=44

To solve the given equations and inequalities step-by-step, let's break them down.

Solve the inequality: \( ax - 44 < 15 \)

  1. Isolate the variable term: To isolate the term \( ax \), add \( 44 \) to both sides: \[ ax < 15 + 44 \] Resulting in: \[ ax < 59 \]

  2. Solve for \( x \): Divide both sides by \( a \) (assuming \( a \neq 0 \)): \[ x < \frac{59}{a} \]

Solve the equation: \( ax + 15 = 44 \)

  1. Isolate the variable term: To isolate \( ax \), subtract \( 15 \) from both sides: \[ ax = 44 - 15 \] Resulting in: \[ ax = 29 \]

  2. Solve for \( x \): Divide both sides by \( a \) (assuming \( a \neq 0 \)): \[ x = \frac{29}{a} \]

Final Results:

  1. For the inequality \( ax - 44 < 15 \):

    • Result: \( x < \frac{59}{a} \)
  2. For the equation \( ax + 15 = 44 \):

    • Result: \( x = \frac{29}{a} \)

Fill in the response areas accordingly with the above simplifications.
