The x intercept is at (12,0). To find it, start with the equation 1.5x + 4.5y = 18, and subtract 1.5x from both sides. This gives you 4.5y = -1.5x + 18. Next, divide everything by 4.5, resulting in y = -1/3x + 4. Hence, the slope of the line is -1/3, and the y intercept is at (0,4). To determine the x intercept, set y to 0. Plugging this into the equation yields: 1.5x + 4.5(0) = 18, simplifying to 1.5x = 18. Dividing both sides by 1.5 gives x = 12.

The slope is -1/3. By subtracting 1.5x from both sides, you are left with 4.5y = 18 - 1.5x. When you divide everything by 4.5, it simplifies to y = 4 - 1/3x. The slope is the coefficient that multiplies x.

Response:

C. 50.24 inches

Detailed explanation:

The area of a circle can be expressed with $\pi r^{2}$ . To determine the circumference, knowing the radius is essential; thereafter, we can substitute that value into the circumference formula $2\pi r$ . Hence, to ascertain the radius, we observe that:
