Find th equation of the line below.If necessary, use a slash to indicate a division bar..(2,14) (1,7)

Answers

$(2,14), \ \ (1,7)\n\n\n First \ find \ the \ slope \ of \ the \ line \ thru \ the \ points \: \n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) \n \nm=( 7-14)/(1-2) = ( -7)/(-1)=7 \n \n Use \ point \ form \ of \ a \ line\ with \ one \ point: \n \n y-y_(1) =m(x-x _(1)) \n \nm=7, \ \ x_(1)=2, \ \ y_(1)=14\n\ny-14 =7(x-2)\n\ny = 7 x-14+14 \n\n y=7x$

General equation for line:
y=ax+b
Putting those points to equation:
(2,14)
14=a*2+b
(1,7)
7=a+b
From substituting method:
a=7-b
14=(7-b)*2+b
14=14-2b+b
b=0
a=7
y=7x - result

A vendor has 30 umbrellas to sell. He sells them for $20 each. The function m(u) = 20u models the total amount of money the vendor makes from selling u umbrellas. What are the practical domain and range of the function?

Answers

Answer:

Step-by-step explanation:

Domain={0,30},Range={0,600

Total number of umbrellas=3

Price for each umbrella is =$20

m(u)=20u

as we know

u = umber of umbrellas

m(u) total amount vendor makes by selling u number of umbrellas

So Practically,The extreme cases are

when the vendor sells 0 umbrellas/ no umbrellas

when he sells all the umbrellas

So Domain is {0,total number of umbrellas}={0,30}

Putting this extreme value of domains as u in function m(u),

we get the range of m(u)={0$20,30$20}

⇒ Range={0,$600}

Answer:

domain 0,30 range 0,600
