Answer:
(x + 3)² + ( y - 1)² = 81
Step-by-step explanation:
To go in reverse, you need to remember that in the equation:
(x - a)² + (y - b)² = r²
a is the x coordinate of the centre and b is the y coordinate of the centre.
As -3 is the x coordinate, we can replace a with 3, and then replace b with 1:
(x - -3)² + (y - 1)² = r²
The two negatives change to a positive:
(x + 3)² + ( y - 1)² = r²
If r is already given as 9, r² is simply 9²
(x + 3)² + ( y - 1)² = 9²
(x + 3)² + ( y - 1)² = 81
So the equation of the circle is (x + 3)² + ( y - 1)² = 81

From 5 to 100 is 10 (10,20,30,40,50,60,70,80,90,100)
from 110 to 200 is another 10
10+10=20
20 numbers
Area of the 3 rectangles that make up the prism:
30 * 25 + 30 * 17 + 30 * 28 = 2100
Area of the two triangles at either end:
Use bh/2
(15 * 28)/2 = 210
There are two so it’s 420
2100 + 420 = 2520cm^2
The 1=2 Glitch isn't patched yet, But the greatest on the Brainly team are trying to work on it. It'll be done before you know it.^﹏^
Answer:
y = -x + 6
Step-by-step explanation:
you will carry the character "X" to the right hand side making it "-x"
