When Lauren left her house in the morning her cell phone battery was partially charged the charge remaining in Lawrence battery as a percentage can be modelled by the equation B equal 63 - 70where T is the number of hours since Lauren left her house what is the X intercept of the equation and what is its interpretation in the context of the problem

Intercept of the equation = (9,0)

Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)

Step-by-step explanation:

Given: When t= the number of hours since Lauren left her house, the charge remaining in Lauren's battery, as a percentage, can be modeled by the equation B=63-7t .

To find the x-intercept, put B =0  (as x denoted the independent variable , here independent variable is 't')

Hence, the x-intercept of the equation = (9,0)

i.e. Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
