a tech store sells laptops (x) for $800 and tablets (y) for $400, with total sales amounting to $8,000, as given by the equation 800x + 400y = 8000. which of the following is the meaning of the x-intercept?

the x-intercept is where an equal amount of laptops and tablets was sold.

the x-intercept is the number of laptops sold when zero tablets were sold.

the x-intercept is the number of tablets sold when zero laptops were sold.

the x-intercept is 8000 laptops sold.

Explanation:

The x - intercept of a linear equation \(Ax + By = C\) is found by setting \(y = 0\) and solving for \(x\). In the context of the equation \(800x+400y = 8000\), when \(y = 0\) (i.e., no tablets are sold), we are left with \(800x=8000\), which gives the number of laptops sold.

Answer:

The x - intercept is the number of laptops sold when zero tablets were sold.
