When Lily left her house in the morning, her cell phone battery was partially charged. The charge remaining in Lily's battery, as a percentage, can be modeled by the equation B=-4t+52,B=−4t+52, where t is the number of hours since Lily left her house. What is the x-intercept of the equation and what is its interpretation in the context of the problem?

The x-intercept of the equation is 13 and its interpretation in the context of the problem is the number of time in hours for which Lily left her house.What is x-intercept?In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).Next, we would determine the number of time for which Lily has left her house since in the morning by substituting the value of B with zero (0) as follows:B = -4t + 520 = -4t + 524t = 52Time, t = 52/4Time, t = 13 hours.Therefore, the x-intercept of the given equation is (0, 13).Read more on x-intercept here: https://brainly.com/question/18649322#SPJ1
