A city council wants to a construction company to pipes underground connecting two locations on Main Street, represented by F and G the map below. The pipes can be installed either along Main Street or in City Park along overline FJ andGJ. the information in the table below to determine the least expensite construction method.
On the map, Quadrilateral FGHK is a rectangle with GH=HJ=JK=KF=400 feet. Based on this information, which decision will result in the LEAST expensive construction method?

answer: about 22.67

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.

i think it’s c i believe
