Answer:

There are 2 solutions to this equation

$x=-\frac{1}{4} +i\frac{\sqrt{19} }{4} ,x=-\frac{1}{4} -\frac{\sqrt{19} }{4}$

Step-by-step explanation:

for a quadratic equation of the form ax^2 + bx + c = 0 the solutions are

$x_{1,2}=\frac{-b±\sqrt{b^{2}-4ac } }{2a}$

$x=\frac{-2+\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4}+ i\frac{\sqrt{19} }{4} \\x=\frac{-2-\sqrt{2^{2}-4.4.5 } }{2.4} :-\frac{1}{4} -i\frac{\sqrt{19} }{4}$

Katyanochek1 [597]

We just add these numbers all together. The "losses" are negatives and the profits are positive.

-140,000 - 56,000 + 110,000 + 60,000 = -26000 or D

The mean of 100 numerical observations is 51.28 what is the value of the sum of all 100 numbers

zlopas [31]

$\dfrac{x_1+x_2+\cdots+x_{99}+x_{100}}{100}=51.28$

which means the sum of the 100 numbers must be

$x_1+x_2+\cdots+x_{99}+x_{100}=100\times51.28=5128$

Solve for x.<br> x + 7/6 = 2x - 7/6

storchak [24]

X + 7/6 = 2x - 7/6

x + 7/6 (-7/6) = 2x - 7/6 - (7/6)

x = 2x - 14/6

x (-2x) = 2x (-2x) - 14/6

-x = -14/6

x = 14/6 or 2.33

x = 2.33

hope this helps
