Answer:
a) 5/2
b) 1/3
Step-by-step explanation:
a) 3y-2x=5 to find the value of y let we replace x by 0
then solve it
B. {(-3,2), (-2,3), (-1,2), (0,4), (1,1)}
5 is a common factor on both of them
we are given
![C(x)=200+10x+0.2x^2](https://tex.z-dn.net/?f=C%28x%29%3D200%2B10x%2B0.2x%5E2)
part-A:
Since, x is number of tablets
C(x) is cost of producing x tablets
so, vertical box is C(x)
so, we write in vertical box is "cost of producing x tablets"
Horizontal box is x
so, we write in horizontal box is "number of tablets"
part-B:
we have to find average on [a,b]
we can use formula
![\frac{C(b)-C(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7BC%28b%29-C%28a%29%7D%7Bb-a%7D)
we are given point as
a: (15 , 395)
a=15 and C(15)=395
b: (20, 480)
b=20 , C(20)=480
now, we can plug values
![=\frac{480-395}{20-15}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B480-395%7D%7B20-15%7D)
...........Answer
part-c:
we have to find average on [b,c]
we can use formula
![\frac{C(c)-C(b)}{c-b}](https://tex.z-dn.net/?f=%5Cfrac%7BC%28c%29-C%28b%29%7D%7Bc-b%7D)
we are given point as
b: (20, 480)
b=20 , C(20)=480
c:(25,575)
c=25 , C(c)=575
now, we can plug values
![=\frac{575-480}{25-20}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B575-480%7D%7B25-20%7D)
