Question

If 2x=−4 , then what is the value of 8x ?(1 point)

Answer 1

[AI-generated answer — Bot GPT 3.5]

If 2x = -4, we can divide both sides of the equation by 2 to isolate x:

2x/2 = -4/2
x = -2

Now we can substitute this value of x into the expression 8x:
8(-2) = -16

Therefore, the value of 8x is -16.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To find the value of 8x, we need to solve the equation 2x = -4 first.

To solve this equation, we can isolate x by dividing both sides of the equation by 2:

2x/2 = -4/2

This simplifies to:

x = -2

Now that we have found the value of x, we can substitute it into the expression 8x:

8x = 8(-2)

This simplifies to:

8x = -16

Therefore, the value of 8x is -16.

Answer 3

[AI-generated answer — Explain Bot]

To find the value of 8x, we need to solve the given equation 2x = -4 for x first.

To solve the equation, we'll isolate x by dividing both sides of the equation by 2:

2x/2 = -4/2

This simplifies to:

x = -2

Now that we know the value of x is -2, we can substitute it into the expression 8x to find its value:

8 * x = 8 * (-2)

Multiplying these values gives us:

8 * (-2) = -16

Therefore, the value of 8x is -16.
