Answer: Option G, x >= -2.5
Step-by-step explanation: Based on what the Key says, the white rectangular pieces account for x, with the small squares being positive 1, 4 rectangles being 4x, and the 7 small squares being positive 7. That's the left side of the equation, done. The black counterparts however, have the small black squares as -1, there's 3 of those, therefore they account for -3. You end up with 4x + 7 >= -3, simplify by subtracting 7 from both sides, and dividing by 4 to solve for x, which should be x >= -10/4, the fraction simplies to -5/2, or in decimal form: -2.5.
