The equation is y=-9x-1
Hope this helps!
Answer:
Step-by-step explanation:
3x + 3y = -3 given
3x = -3y - 3 subtract 3y from both sides
x = -y -1 divide everything by 3

Answer:
21.5cm²
Step-by-step explanation:
First you find out the Area of the square itself which is 100cm² (squared). Then you Find the Area of the circle. The formula to find the area of a circle is π × Radius². So you find the diameter of the circle (which is 10) and divide that by 2 to find the radius. So the radius is 5 but then you need to square 5 which is 25. Then you multiply 25 with pi which is 78.5 so the area of the circle is 78.5cm². Now what you have to do is subtract the area of the square and the area of the circle to find the area of the shaded region. 100-78.5 is 21.5cm ² and that is the answer.
So hmm notice the picture below
simply get the area of the segment, and subtract it from the area of the circle, what's left, is the difference
notice your circle, has a radius "r" of 18
