So you always want y in front of the equation no matter what so you have x +2y=5 so you take the x and you subtract it to both side making it 2y= 5-x so then you just have to take the 2 to both side so you have to divide it and you will get y= 5/2-x/2 so then to graph it you start with the b which is -x/2 so you go down -1 and over 2 and place your dot adn then go up 5 over 2 and then place you dot and connect them together
See the graph in the attached image.
Answer:
56
Step-by-step explanation:
This picture is a square and inside the square we can see 4 piece of a circle.
The area of a piece of a circle=1/4 (area of a circle with radius = 9 m/2=4.5 m)
Therefore:
the area of a 4 piece of a circle=area of a circle with radius=4.5 m).
Area of the shaded region=area of the square -area of a circle.
1) we compute the area of the square:
area of a square=side²
Data:
side=9 cm
Area of this square=(9 m)²=81 m².
2) we compute the area of a circle with 4.5 m of radius.
area of a circle=πr²
area of this circle=π(4.5 m)²=20.25π m²
3) we calculate the area of the shaded region:
area of the shaded region=area of the square - area of the circle
area of the shaded region=81 m²-20.25π m²≈17.38 m²
Area= about 17.38 m²
