Answer:

The solution to this equation could not be determined! (O>O)

Step-by-step explanation:

Simplifying

4x2 + 6x + 12 = 0

Reorder the terms:

12 + 6x + 4x2 = 0

Solving

12 + 6x + 4x2 = 0

Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '2'.

2(6 + 3x + 2x2) = 0

Ignore the factor 2, I think this is a 'trick' question !

Determine whether the integral is convergent or divergent. ∫[infinity] 2 e^−1/x / x^2 dx : O Convergent O divergent If it is con

monitta

Let $f(x)=e^{-1/x}$ . Then $f'(x)=\frac1{x^2}e^{-1/x}>0$ for all $x\ge2$ , so $f$ is strictly increasing. As $x\to\infty$ , $e^{-1/x}\to e^0=1$ , so $f$ is bounded above by 1. This is to say,

$e^{-1/x}$

and the integral of $\frac1{x^2}$ converges over the same domain, so this integral must also converge by comparison.

We have, by setting $y=-\frac1x$ ,

$\displaystyle\int_2^\infty\frac{e^{-1/x}}{x^2}\,\mathrm dx=\int_{-1/2}^0e^y\,\mathrm dy=e^0-e^{-1/2}=1-\frac1{\sqrt e}$

Solve [(x+7) x 3-5] / 4 = 7<br> What is the first step in this equation

Nitella [24]

Answer:

The first step is to slove the numbers in the brackets

Step-by-step explanation:

[(x+7) x -2] / 4 = 7

-2(x+7) / 4 = 7

-2x-14 / 4 = 7

-2x-14 = 28

-2x = 42

x = -21

3 Shamaya went shopping for school supplies. She bought 2 packages of

allsm [11]

Answer:

a. $17.83

b. $82.17

Step-by-step explanation:

We need to find total cost of all the items.

2 package of pencil for 1.98 each: Total = 1.98 * 2 = 3.96

1 binder for 7.69: Total = 7.69

1 divider for 2.69: Total = 2.69

1 pencil box for 3.49: Total = 3.49

We sum all of these to get:

3.96 + 7.69 + 2.69 + 3.49 = $17.83

She only spent 17.83 and she had 100 dollars. So we subtract amount spent (17.83) from total (100) to get remaining balance.

100 - 17.83 = $82.17
