ER A store has two types of animal feed available. Type A contains 3 pounds of oats and 3 pounds of corn per bag. Type B contains
1 pound of oats and 7 pounds of corn per bag. A farmer wants to combine the two types so that the resulting mixture has at
least 18 pounds of oats and at least 54 pounds of corn. The store only has 11 bags of type A feed and 12 bags of type B feed in
stock. Type A costs $3 per bag, and type B costs $5 per bag. How many bags of each type should the farmer buy to minimize
his cost?

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

step-by-step explanation:

answer: x=1

step-by-step explanation:

f(x) = g(x)

x - 2 = -1

x = 1

therefore the graph should be a line showing x=1 which is vertical and passes on 1

hope it !

since there are the same amount of marbles of getting a blue one wold be low as far from that it would also be low!    

*hope this : d*
