Answer: -4 \le x \le 5
Note: to write the domain in interval notation, you'd write [-4,5]
if you need the domain in set-builder notation, then you'd write \left\{x|x\in\mathbb{R}, \ -4\le x\le 5\right\}

------------------------------------------------------------------------------

Explanation:

The domain is the set of possible x input values. Look at the left most point (-4,-1). The x coordinate here is x = -4. This is the smallest x value allowed. The largest x value allowed is x = 5 for similar reasons, but on the other side of the graph.

So that's how I got -4 \le x \le 5 (x is between -4 and 5; inclusive of both endpoints)

Writing [-4,5] for interval notation tells us that we have an interval from -4 to 5 and we include both endpoints. The square brackets mean "include endpoint"

Writing \left\{x|x\in\mathbb{R}, \ -4\le x\le 5\right\} is the set-builder notation way of expressing the domain. The x\in\mathbb{R} portion means "x is a real number"

An airliner is 9.34 feet wide. The airline wants to install 5 seats in each row. The seats are each 1.46 feet wide. Rounded to t
MatroZZZ [7]

About 2.0 feet space will be left for aisle.

Step-by-step explanation:

Width of airliner = 9.34 feet

Width on one seat = 1.46 feet

Seats to install = 5

Width of 5 seats = 5*1.46 = 7.3 feet

Space left for aisle = Width of airliner - width of 5 seats

Space\ left\ for\ aisle=9.34-7.3\\Space\ left\ for\ aisle=2.04\ feet

Rounding off to nearest 10th

Space left for aisle = 2.0 feet

About 2.0 feet space will be left for aisle.
