Subtract 12 from the side of x and moving it to 40, creating x<28
Answer:
The weight of luggage for a flight with 142 passengers is 2,106
Step-by-step explanation:
The total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation:
y=118+14*x
where y is the total weight of luggage stored in the luggage compartment and x is the number of passengers on a bus.
If you want to predict the weight of luggage for a flight with 142 passengers, this means that x must have a value of 142. So, replacing in the expression:
y=118+14*142
you get:
y=118+1,988
y=2,106
The weight of luggage for a flight with 142 passengers is 2,106
Set the equation inside the absolute value brackets equal to 12 and -12, so you will end up with two answers.
7x+2=12 gives you 10/7
7x+2=-12 gives you -2.
So your answers are 10/7 and -2
