Answer:

B). (1,8)

Step-by-step explanation:

You can build graphical using both equation

  1. y=x+7
  2. y=-2x+10

1. When y=0, so x=-7 and when x=0, so y=7

2. When y=0, so x=5 and when x=0, so y=10  

So in the image graphic 1 is red and graphic 2 is blue and you can see they cross at (1,8)

To check

1=2 so, x+7=-2x+10 \\ 3x=3 \\ x=1

Replacing:

1. y=1+7=8 and 2. y= -2*1 +10=8

So (1,8)

A swimming pool has a diameter of 24 feet. What is the minimum amount of fabric needed to cover the pool if the cover must hang
Alika [10]

Answer:

531.167 ft²

Step-by-step explanation:

Given data

Dimension of pool

Diameter =24ft

Radius =12ft

If the cover must hang by 1ft around, then the diameter is 26ft

Radius =13ft

Area of cover = πr²

Substitute

Area = 3.142*13²

Area =3.143*169

Area =531.167 ft²

Hence the minimum area is 531.167 ft²
