Area of a circle = (3.14) * r^2
d = 7
r = 3.5

a = (3.14) * 3.5^2
a = (3.14) * 12.25
a = 38.47

Solve with completing the square method: 6x²-7x+2=0 and ax²+bx+c=0

Norma-Jean [14]

$6x ^2-7x+2=0\\ \\ a=6 , \ b = -7 , \ c=2 \\ \\\Delta = b^{2}-4ac = (-7)^{2}-4*6*2=49-48=1 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{7-\sqrt{1}}{2*6}=\frac{7-1}{12} =\frac{6}{12}= \frac{1}{ 2}\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{7+\sqrt{1}}{2*6}=\frac{7+1}{12} =\frac{8}{12}= \frac{2}{ 3}$

Which graph best represents the following equation Y+4=|x+2|

oksian1 [2.3K]

The first one as when |x+2| the graph would be from x=-2 "shifting left by 2" and then we subtract 4 from both sides so Y=|x+2|-4 and this accounts for shifting the graph four units down.
