Answer:
x-y=4
Step-by-step explanation:
y=x−4
The standard form of a linear equation is
Ax+By=C.
Rewrite the equation with the sides flipped.
x−4=y
Move all terms containing variables to the left side of the equation.
Tap for more steps...
x−y−4=0 Add 4
to both sides of the equation.
x−y=4

Answer:
942 6/7 cm²
Step-by-step explanation:
Since O = Center of bigger circle, OA = Radius of bigger circle.
∴ Area of smaller circle - Area of bigger circle = Area of shaded part.
∴ Area of smaller circle = 22/7 × 10²
= 22/7 × 100
= 2200/7
= 314 2/7 cm²
∴ Area of bigger circle = 22/7 × 20 ²
= 22/7 × 400
= 1257 1/7 cm²
∴ Area of shaded part = 1257 1/7 - 314 2/7
= 942 6/7 cm²
