Answer:
15.35 m²
Step-by-step explanation:
For a central angle of θ in radians, the area of a segment is ...
A = (1/2)r²(θ -sin(θ))
The central angle subtending the segment is 120°, or 2π/3 radians. Thus the segment area is ...
A = (1/2)(5 m)²(2π/3 -sin(2π/3)) = (25 m²)(π/3 -(√3)/4)
A ≈ 15.35 m² . . . . area of shaded segment
You first have to turn 2x + 4y = -8 into y = mx + b before graphing. To do this, you subtract 2x from the left side of the equation because inverse operations. This will bring 2x to the right side. Now, you will have 4 = -2x + 8. However, you cannot have a number with y. Therefore, you must divide -8 and 2 by 4. You will get y = -1/2 x + 2 as your equation.
To graph -1/2x + 2, you must remember rise/run. Since it is NEGATIVE -1/2, your slope will go downwards (1 down, 2 across) starting from y = 2.
Answer:
Step-by-step explanation:
y=2/5x+2
x= 5/2y-5
hopefully this works
X=-2 is shown on the graph.
