Answer:
The answer to your question is: y = -3x + 14
Step-by-step explanation:
Data
A (4, 2)
y = x/3 - 1
Perpendicular
original slope = 1/3
perpendicular slope = -3
Equation (y - y1) = m(x - x1)
(y - 2) = -3(x - 4)
y - 2 = -3x + 12
y = -3x + 12 + 2
y = -3x + 14
Hey there,
I believe but I'm not quite sure, I believe that the correct answer would be 42 because by subtracting 79-37, that should give you y.
Hope this helps. (forgive any errors.)

Answer:
8 is the answer
Step-by-step explanation:
----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the semicircle = 10 ÷ 2 = 5cm
----------------------------------------------------------------
Find Area of the semi circle :
----------------------------------------------------------------
Area of the semi circle = 1/2 πr²
Area of the semi circle = 1/2 x π x (5)²
Area of the semi circle = 12.5π cm²
----------------------------------------------------------------
Find Radius :
----------------------------------------------------------------
Radius of the inner circle = 5 ÷ 2 = 2.5 cm
----------------------------------------------------------------
Find area of inner circle :
----------------------------------------------------------------
Area of the inner circle = πr²
Area of the inner circle = π x (2.5)²
Area of the inner circle = 6.25π
----------------------------------------------------------------
Area of the shaded region :
----------------------------------------------------------------
Area of the shaded region = 12.5π - 6.25π
Area of the shaded region = 6.25π
Area of the shaded region = 19.63 cm²
----------------------------------------------------------------
Answer: Area of the shaded region = 19.63 cm²
----------------------------------------------------------------
