3(x-4)>= 5x+2

Distributing 3 on x-4

3(x)-3(4)>=5x+2

3x-12>=5x+2

Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides

-2x >=14

Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is

x<=-7

Answer:

Below in bold.

Step-by-step explanation:

c) 3 x (9^2)^3/4 x ((81^3)^5/6

= 3 x 81^3/4 x 81^15/6

= 3 x 81^(3/4 + 15/6)

= 3 x 81^13/4

= 3 x 3^13

= 3^14

= 4,782,969.

f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2

= 5^-2 x^2y^-4 / 625 x^4y^-2

= 5^-2 x^-2 y^-2 / 5^4

= 5^-6 x^-2y^-2

= 0.000064x^-2y^-2.

While performing a vertical line test on a graph, you notice that the graph intercepts the vertical line twice. Which of the fol

MakcuM [25]

Answer:

The correct option is;

Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function

Step-by-step explanation:

Given that a function maps a given value of the input variable, to the output variable, we have that a relation that has two values of the dependent variable, for a given dependent variable is not a function

Therefore, a graph in which at one given value of the input variable, x, there are two values of the output variable y is not a graph of a function

With the vertical line test, if a vertical line drawn at any suitable location on the graph, intercepts the graph at more than two points, then the relationship shown on the graph is not a function.

Question 8. PV = nRT, solve for T please?<br><br>Question 10. C= Wtc÷1000, solve for W, please?

Answers:

$\huge \boxed{T= \frac{P V}{n R} } \\ \\ \\ \\ \huge \boxed{W= \displaystyle \frac{1000C }{tc}}$

$\rule[225]{225}{2}$

Step-by-step explanation:

$P \cdot V = n \cdot R \cdot T$

Dividing both sides by n · R:

$\displaystyle \frac{P \cdot V}{n \cdot R} =T$

$\displaystyle C=\frac{Wtc }{1000}$

Multiplying both sides by 1000:

$1000C=Wtc$

Dividing both sides by tc:

$\displaystyle \frac{1000C }{tc}=W$

<h2 />

$\rule[225]{225}{2}$

A thumb-wrestling match requires two thumbs, so we can either suppose that we need at least two people $(n\ge2)$ , or allow one to thumb-wrestle one's self. In either case, we'd have $t(1)=t(2)=1$ , so let's just say we need a minimum of two players.

If we add one more person to the set of players, then the first two people would need to play 1 additional match each. So $t(3)=t(2)+2$ .

If we add one more person, then the first three people would again each have to play 1 more match with the new person. So $t(4)=t(3)+3$ .

And so on, so that in general, the number of games needed for everyone to play exactly one match with everyone else is given recursively by

$\begin{cases}t(2)=1\\t(n+1)=t(n)+n&\text{for }n\ge2\end{cases}$
