First, you have to find the area of the rectangular swimming pool (A1), which has <span>10 feet long and 6 feet wide. The area of a rectangle is:

 A=A1=LxW

 L=10 ft
 W=6 ft

 When you substitute these values into the formula, you obtain:
</span>
 A1=LxW
 A1=(10 ft)(6ft)
 A1=60 ft²

 The area of the Andrea’s backyard (A2) is 400 ft², therefore, the<span> area of Andrea’s backyard, not including the swimming pool (A3), is:

 A3=A2-A1
 A3=400 ft</span>²-60 ft²
 A3=340 ft²
<span>
 What is the area of Andrea’s backyard, not including the swimming pool?

 The answer is: T</span>he area of Andrea’s backyard, not including the swimming pool, is 340 feet²

Find the coordinates of the points of intersection of the graphs with coordinate axes: y=− 1/4 x+2
bearhunter [10]

Answer:


Step-by-step explanation:

Here, you can use a simple formula.

To find the point of intersection you just put x=0 or y=0.

Because, if a graph intersects x-axis, then at this point  y=0

Similarly, if a graph intersects y-axis, then at this point  x=0


So, for our given line.

y=-1/4 x +2

when , x=0 , y=-1/4 (0)+2=2

So, the graph intersects y-axis at   y=2


when , y=0 ,

then    0=-1/4 x+2

       or, 1/4 x=2

       or, x=8    [multiplying by  4]

So, the graph intersects x-axis at   x=8
