Question

X intercept the graph of
3x+12=-6

Answer 1

`3x + 12 = - 6 \\x + 12 = - 6 * 3 \\ x + 12 = - 18 \\ x = - 18 - 12 \\ x = 30`

Answer 2

-2

Explanation:

The x-intercept of the graph of 3x + 12 = -6 is -2 (option B). The value of x at the x-intercept is -2. This means that the graph intersects the x-axis at the point (-2, 0). When x equals -2, the equation 3x + 12 = -6 results in y = 0, which is the definition of the x-intercept.
