Answer:

Step-by-step explanation:

If there are options, please share them.

Subtract 7 from both sides. We obtain: -2x^2 + 3x - 3. The coefficients of this quadratic are a = -2, b = 3 and c = -3. Thus, the discriminant is

b^2 - 4ac, or 3^2 - 4(-2)(-3), or 9 - 24, or -15. Because the discriminant is negative, this quadratic has two complex roots which differ:

-3 ± i√15

x = -----------------

-4

The current value of an investment is 125 percent of its initial value.The increase in value is $10million.What was the initial

kicyunya [14]

Answer:

$40 million

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Current value = 125%

which means that current value is 25% more than its initial value.

Let Initial Value = X

So, Increase in investment value = 25% × X = 0.25X

Given, increase value = $10million

So, 0.25X = $10 million

= X = $10million

= X = $10million ÷ 0.25

= X = $40 million

Hence the initial value of investment is $40million.
