Answer:
b= -8
Step-by-step explanation:
we have: 3y +12 = 6x <=> y + 4 = 2x <=> y= 2x - 4
=> 2y=4x + b
<=> 2(2x-4) = 4x +b
<=> 4x - 8= 4x +b
<=> b = -8
I think there is no simplified fractions for this number it will be the same -4/17
Answer:
~4.7%
Step-by-step explanation:
Area of the rectangle: 35*52=1820
Area of 1 small circle: A=πr2=π·32≈28.27433
28.27433*3=84.82299
84.82299/1820=0.04660603846
Therefore, about 4.7%
Answer: C
Step-by-step explanation:
x = 2
- 6
x + 6 = 2
((x+6)/2 =
)^2
(x+6/2)^2 = y+2
y = (x+6/2)^2 -2
y= 1/4x^2 +3x +7
