Answer:

The solution is x = + 0.77 , -0.77

Step-by-step explanation:

The equation is

$x^3 - 3x^2 - 4 = \frac{1}{x} -1 +5\\x^4 -3x^3 -4x = 1-4x\\x^4 - 3x^3 = 1\\x^3 (x-3) = 1\\\\x^4 -3x^3 -1 = 0\\x^4 -3x^3 -1$

The solutions to the equation is

x = + 0.77 , -0.77

Which ordered pair is the best estimate for the solution to the system

Vera_Pavlovna [14]

Answer:

The best estimate of the solution ordered pair from the graph is $(\frac{1}{2},0)$ .

Step-by-step explanation:

See the attached graph to this question.

The graph of two straight lines are shown in the graph.

Now, the two straight lines intersect on the x-axis, so the solution ordered pairs should have y-value equals to zero.

But, there are two ordered pairs with y-value zero and they are $(\frac{1}{2},0)$ and $(\frac{1}{3},0)$ .

The best estimate of the solution ordered pairs from the graph is $(\frac{1}{2},0)$ .

So, this is the solution. (Answer)

10 is 32% of what number?

Fantom [35]

Answer:

x= 3,2

Step-by-step explanation:

10 ---------------- 100%

x ---------------- 32%

$x=\frac{10\times32\%}{100\%}$

$x=\frac{10\times32}{100}$

$x=\frac{320}{100}$

$x=\frac{32}{10}$

$x=\frac{32\div2}{10\div2}$

$x=\frac{16}{5}$

$x=3,2$
