Use a graphing calculator. Solve 5.53x = 805 by graphing. Round to the nearest hundredth.
a) 2.91
B) 3.92
C) 1.31
D) 0.97
To solve the equation 5.53x = 805 by graphing, we need to plot the graph of the equation y = 5.53x and the line y = 805 on a graphing calculator.
To do this, follow these steps:
1. Press the "Y=" button on the graphing calculator.
2. Enter the equation 5.53x in the first equation slot.
3. Press the "ENTER" button.
4. Enter the equation 805 in the second equation slot.
5. Press the "GRAPH" button to see the graph of the two equations.
The intersection point of the two graphs represents the solution to the equation 5.53x = 805.
By observing the graph, it is clear that the intersection point is approximately x = 2.91. Therefore, the correct answer is A) 2.91.
