Need fast answer im ! you want to build a fence in your back yard for a rectangular garden. the garden will be up against your house, so you only need three sides to your fence. the long side (the length) will be along the wall. (feel free to draw a diagram on paper like we did for the review problem.) if you want the length to be twice the width, and if you have 44 feet of fence, what will the length be? your answer will be in feet, but just type the number. do not type the word "feet". do not type "l=". hint: write equations for the total length of fence around the garden and for the length in terms of the width. plug in the information that you know and solve your equation. check yourself when done by rereading the problem and see if your answer works.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
