Question

The director wants to know whether the drummer will cross the x-axis at a point where the x-coordinate is greater than or less than 5. Explain how the director can answer this question. When the drummer crosses the x-axis, the y-coordinate will be ______, so solve 0 = -23x + 113 to find the x-coordinate. Solving shows that x = 112 or 12, so the x-coordinate will be greater than ______.

Answer 1

The drummer will cross the x-axis at a point where the x-coordinate is greater than 5.

Step-by-step explanation:

To determine whether the drummer will cross the x-axis at a point where the x-coordinate is greater than or less than 5, we need to solve the equation 0 = -23x + 113 to find the x-coordinate. Solving the equation, we get x = 112 or x = 12. Since both values are greater than 5, the x-coordinate will be greater than 5 when the drummer crosses the x-axis.
