For this case, the first thing you should do is find the area of the room. We can assume that the room is a rectangle, then the area will be:
 A = (w) * (l)
 Where,
 w: width
 l: long
 Substituting the values we have:
 A = (16) * (20)
 A = 320 feet ^ 2
 We note that each carpet covers only 4 feet ^ 2.
 Therefore the number of carpets will be:
 N = (320) / (4)
 N = 80
 Answer: 
 andy will need to buy 20 carpet squares to cover the room

Answer:

y=-3x+2

Step-by-step explanation:

Slope-intercept form is given by the equation y=mx+b, where m is defined as the slope and b is defined as the y-intercept (the value on the y-axis that the line crosses). First we can determine the slope by using the slope formula.

m=(y2-y1)/(x2-x1), given two points (x1, y1) and (x2, y2). Keep in mind you can choose which point is (x1,y1) and which is (x2,y2) as long as you are consistent.

Plugging in for (-1,5) and (1,-1), you will get:

m=(-1-5)/(1-(-1))=-6/2=-3

Next, we need to find the y-intercept. For this problem, you can determine it is 2 by looking at the graph of the line. We now have both components to create the slope-intercept form.

m=-3, b=2

y=-3x+2

Consider the following. y = x2 y = 20 − x Maple Generated Plot (a) Find the area of the region by integrating with respect to x.
Hunter-Best [27]

Answer:

  area = 121.5

Step-by-step explanation:

See below for a plot and the integral. We assume you are interested in the entire bounded region.

__

  \displaystyle\text{area}=\int_{-5}^4{(20-x-x^2)}\,dx=\left.20x-\dfrac{x^2}{2}-\dfrac{x^3}{3}\right|_{-5}^4\\\\=20(4-(-5))-\dfrac{4^2-(-5)^2}{2}-\dfrac{4^3-(-5)^3}{3}\\\\=180+\dfrac{9}{2}-63=121.5
