The revenue equation (in hunderds of millions of dollars) for barley production in a certain country is approximated by r(x) 0.0654x1.4118x 2.0836 where x is in hundreds of millions of bushels. find the marginal-revenue equation and use it to find the marginal revenue for the production of the given number of bushels (a) the marginal-revenue equation is r') round to four decimal places as needed.) (b) find the marginal revenue for the production of 300,000,000 bushels the marginal revenue is hundred million dollars. (type an integer or decimal rounded to two decimal places as needed.) (c) find the marginal revenue for the production of 750,000,000 bushels the marginal revenue is ? hundred million dollars. (type an integer or decimal rounded to two decimal places as needed.)

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

step-by-step explanation:

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.
