Answer:

The answer is 3x....

Step-by-step explanation:

Lets re-write the given expression:

3/x² ÷ 1/x³

Now we know that the division will be changed into multiplication and the denominator of the second term will become numerator.

3/x² * x³/1

Now the expression becomes:

3x³/x²

According to the laws of exponents when you divide variables, just find the difference of their exponents. Therefore,

3x³/x² = 3x³-² = 3x

Thus the answer is 3x....

Para la ecuación 2x+5y-3=0, halla la coordenada que falta (-3,?)

butalik [34]

Answer:

$(-3, \frac{9}{5})$

Step-by-step explanation:

We have the equation $2x + 5y-3 = 0$ .

The ordered pairs of this equation have the form $(x_0, y_0)$

Where x is the independent variable and y is the dependent variabe.

That is, the points belonging to the line $2x + 5y-3 = 0$ have the form $(x_0, f (x_0))$

For $y = f(x)$ .

So, we need to find $f(x_0)$ for x_0 = -3.

Then we substitute x = -3 into the equation and clear the value of y.

$2(-3) + 5y -3 = 0$

$-6 + 5y = 3\\\\5y = 9\\\\y = \frac{9}{5}$ .

Then the ordered pair is:

$(-3, \frac{9}{5})$

Help please!<br>figure out the "inflection point" of the following function<br>f(x)=5x³ + 2x² − 3x

Artyom0805 [142]

Answer:

x = -2/15.

Step-by-step explanation:

Finding the second derivative:

f'(x) = 15x^2 +4x - 3

f"(x) = 30x + 4

30x + 4 = 0 for a point of inflection

x = -4/30 = -2/15

So 30x + 4 is negative up to x = -2/15 and positive thereafter.

So the curve passes from concave downward to concave upward at x = -2/15.

Find the solution set for the given inequality. -7x + 3 > 45 A) Show your work to solve this inequality (B) Graph the solutio

scoundrel [369]

Answer:

See explanation

Step-by-step explanation:

Given the inequality $-7x+3>45$

A) Add -3 to both sides of inequality:

$-7x+3-3>45-3\\ \\-7x>42$

Divide by -7 (remember, dividing the inequality by negative number changes the sign of inequality):

$x$

B) Plot open circle at -6 on the number line and shade all values of x which go to the left from -6 (see attached diagram).
