Answer:
Missing co-ordinate for the ordered pair is ![(7,2834)](https://tex.z-dn.net/?f=%287%2C2834%29)
Y-intercept is ![(0,4682)](https://tex.z-dn.net/?f=%280%2C4682%29)
X-intercept is ![(17.73,0)](https://tex.z-dn.net/?f=%2817.73%2C0%29)
Step-by-step explanation:
The number of a certain company's video stores can be approximated by the linear equation
![y= -264\ x+4682](https://tex.z-dn.net/?f=y%3D%20-264%5C%20x%2B4682)
where
is the number of stores and
represents the number of years after 1990.
To find the missing co-ordinate for the ordered pair solution ![(7,?)](https://tex.z-dn.net/?f=%287%2C%3F%29)
For the ordered pair, we are given the
value which is =7 i.e 7 years after 1990. Thus we will plugin
in the linear equation to get the
value which is number of stores after 7 years from 1990.
![y= -264\ (7)+4682](https://tex.z-dn.net/?f=y%3D%20-264%5C%20%287%29%2B4682)
![y= -1848+4682](https://tex.z-dn.net/?f=y%3D%20-1848%2B4682)
![y= 2834](https://tex.z-dn.net/?f=y%3D%202834)
Thus the ordered pair is ![(7,2834)](https://tex.z-dn.net/?f=%287%2C2834%29)
To find y-intercept which is the point where the line touches the y-axis, we would plugin
in the equation as the x-coordinate is 0 at y-axis.
![y= -264\ (0)+4682](https://tex.z-dn.net/?f=y%3D%20-264%5C%20%280%29%2B4682)
![y= 0+4682](https://tex.z-dn.net/?f=y%3D%200%2B4682)
![y=4682](https://tex.z-dn.net/?f=y%3D4682)
Thus y-intercept is at point ![(0,4682)](https://tex.z-dn.net/?f=%280%2C4682%29)
To find x-intercept which is the point where the line touches the x-axis, we would plugin
in the equation as the y-coordinate is 0 at x-axis and thus for ![x](https://tex.z-dn.net/?f=x)
![0= -264\ x+4682](https://tex.z-dn.net/?f=0%3D%20-264%5C%20x%2B4682)
Subtracting both sides by 4682.
![0-4682= -264\ x+4682-4682](https://tex.z-dn.net/?f=0-4682%3D%20-264%5C%20x%2B4682-4682)
![-4682= -264\ x](https://tex.z-dn.net/?f=-4682%3D%20-264%5C%20x)
Dividing both sides by -264
![\frac{-4682}{-264}= \frac{-264\ x}{-264}](https://tex.z-dn.net/?f=%5Cfrac%7B-4682%7D%7B-264%7D%3D%20%5Cfrac%7B-264%5C%20x%7D%7B-264%7D)
![17.73= x](https://tex.z-dn.net/?f=17.73%3D%20x)
∴ ![x=17.73](https://tex.z-dn.net/?f=x%3D17.73)
Thus x-intercept is at point ![(17.73,0)](https://tex.z-dn.net/?f=%2817.73%2C0%29)
Answer:
Step-by-step explanation:
A shopper paid $2.52 for 4.5 pounds of potatoes. This means that the unit price for each potato would be
2.52/4.5 = 0.55556
Approximately $0.6 per pound.
The shopper paid $7.75 for 2.5 pounds of broccoli. This means that the unit price for each broccoli would be
7.75/2.5 = $3.1 per pound.
The shopper paid $2.45 for 2.5 pounds of pears. This means that the unit price for each pear would be
2.45/2.5 = $0.98 per pound
50 + 7/32 = 50 7/32
50 - 7/32 = 49 25/32
answers are :
c.) 49 25/32 < = x < = 50 7/32
e.) |x - 50| < = 7/32
