Hope this helped!
Answer:
B). (1,8)
Step-by-step explanation:
You can build graphical using both equation
1. When , so and when , so
2. When , so and when , so
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,
Replacing:
1. y=1+7=8 and 2. y= -2*1 +10=8
So (1,8)
10 z
Hope this helped :)
you have to use cross-multiplication in order to find out the answer to this question.
9/12 times 2/3
531.167 ft²
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
