Answer:
20xπ units
Step-by-step explanation:
Use the formula for the length of an arc.
θ/360 × 2πr
The length of the arc and the central angle is already given.
18/360 × 2πr = xπ
Solve for r.
r = (xπ)/(18/360)/(2π)
r = 10x
The radius is 10x.
The circumference is 2πr.
2π(10x)
20xπ
The circumference of the circle is 20xπ units.
y - x < 2x + 2
To isolate y, let's add both sides by x.
y - x + x < 2x + 2 + x
y < 3x + 2
That should be your answer for the equation. For the graph, look at the image I attached to my answer~
Happy Studying~
The answer will be 5(m-100) because 5m-100 equal to m-20 which you just need to divided 5. Hope it help!
