How to solve linear equations

i found this on google:

Step-by-step explanation:

To solve linear equations we will make heavy use of the following facts. If a=b then a+c= b+c a + c = b + c for any c . All this is saying is that we can add a number, c , to both sides of the equation and not change the equation. If a=b then a−c=b−c a − c = b − c for any c

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
