Answer 1

Answer: equation 3x (-4) = -12 has a solution of x = 1, which can be represented on the number line between -2 and -3.

Step-by-step explanation: Based on the number line and the answer choices provided, it appears that the equation modeled on the number line is:

C) 3x (-4) = -12

This equation can be interpreted as "what number multiplied by 3 and then multiplied by -4 will give a result of -12". Solving for x, we get:

3x (-4) = -12

-12x = -12

x = -12/-12

x = 1

Therefore, the equation 3x (-4) = -12 has a solution of x = 1, which can be represented on the number line between -2 and -3.
