Answer:
8/5
Step-by-step explanation:
Slope of the line = (-1-4)/(2-0)= -5/2
Equation of the line :
=> y - y1 = m(x - x1)
=> y - 0 = (-5/2)(x - 4)
=> 2(y - 0) = - 5x + 20
=> 2y + 5x = 20
To make the RHS 16, divide both sides by 20 and multiply by 16:
=> (2y/20)*16 + (5x/20)*16 = (20/20)*16
=> 8y/5 + 4x = 16
compare the equation with ax + by = 16 for y, b = 8/5
The area of a whole circle is (pi) (radius²) .
So the area of half of it would be <em>(1/2) (pi) (radius²) .</em>
If you don't know the radius, then you can use the formula
Area = (1/8) (pi) (diameter²) .
3x-5y+6z=4
-3x+9y-15z=15
4y-9z=19
-2x+6y-10z=10
2x- 4y+ z= 13
2y-9z=23
4y-9z=19
-2y+9z=-23
2y=-4
y=-2
3x+10+6z=4
x - 6 +5z=-11
3x+6z=-6
x +5z=-5
3x+6z=-6
-3x-15z=33
-9z=27
z=-3
x+6-15=-5
x-9=-5
x=4
