Answer:
y = -2x + 3
Step-by-step explanation:
[]Let us write an equation in slope-intercept form.
-> See attached
-> Our equation will start out as y = x
[] The slope can be found by taking the change in y divided by the change in x
->
-> Now our equation is y = -2x
[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.
-> y = -2x + b
(1) = -2(1) + b
1 = -2 + b
3 = b
-> Now our equation is y = -2x + 3, which is our final answer.

Answer:
The polynomial for the sum of the shaded r² - 20
Step-by-step explanation:
Given as :
The figure is shown which is of concentric circle with radius B , A , r
The radius B = 4 unit
The radius A = 6 unit
Let The sum of shaded portion = x unit
Now, The circumference of circle = 2 R , where R is the radius
So, for circle with radius B.
The circumference = 2 R = 2
B
Or, The circumference = 2 × 4 = 8
<u>Similarly</u>
For circle with radius A.
The circumference = 2 R = 2
A
Or, The circumference = 2 × 6 = 12
Now, <u>The area of circle with radius r is</u>
Area = ×radius × radius
Or, Area = r²
Now,
The sum of shaded region area = The area of circle with radius r - ( The circumference with radius B + The circumference with radius A )
Or, The sum of shaded region area = r² - ( 8
+ 12
)
Or, The sum of shaded region area = r² - 20
Hence The polynomial for the sum of the shaded area is r² - 20
