Simplify the equation as best you can and then graph it. When you have graphed it, the x-coordinate when y=0 is x.

What two numbers you can add together to give you 27 and also multiply the two numbers to give 60

Vera_Pavlovna [14]

There are none that work, the only close two are 3 and 24 + 2 and 25, but they multiply to 72 and 50, but if you can use decimals, you could use 2.445+24.555

Determine whether each set of ordered pairs shown below is from a geometric sequence or from an arithmetic sequence.

daser333 [38]

Using sequences concepts, it is found that:

The set of ordered pairs {(-3, 7.5) , (-2, 10) , (-1, 12.5)} is an arithmetic sequence with equation a(n) = 15 + 2.5d.

The set of ordered pairs {(1, 150) , (2, 112.5) , (3, 84.375)} is a geometric sequence with $a_n = 150(0.75)^{n-1}$ .

<h3>What is an arithmetic sequence?</h3>

In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.

The nth term of an arithmetic sequence is given by:

$a(n) = a(0) + nd$

The sequence {(-3, 7.5) , (-2, 10) , (-1, 12.5)} continues with points (0, 15), (1, 17.5), and so on, hence the first term and the common ratio are given, respectively, by:

a(0) = 15, d = 2.5.

Hence the equation is:

a(n) = 15 + 2.5n.

<h3>What is a geometric sequence?</h3>

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

$a_n = a_1q^{n-1}$

For the sequence {(1, 150) , (2, 112.5) , (3, 84.375)}, the first term and the common ratio are given, respectively, by:

$a_1 = 150, q = \frac{112.5}{150} = \frac{84.375}{112.5} = 0.75$

Hence the equation is given by:

$a_n = 150(0.75)^{n-1}$

Pls help or explain steps

Tems11 [23]

Solving for a variable means to rewrite the equation so that the desired variable is alone on one side. So, we have to "move" all the other variables/constants in order to make this happen. We are allowed to add/subtract the same quantity from both sides, or to multiply/divide both sides by any non-zero number.

Let's start with the first example: we are given

11. $d=rt$

the variable $r$ is not alone on the right hand side because it is multiplied by $t$ . We can reverse this by dividing both sides by $t$ : the equation becomes

$\dfrac{d}{t}=\dfrac{rt}{t}=r$

So, we have written the equation as $r=\frac{d}{t}$ , which means that $r$ now sits alone on one side of the equation, and thus we have solved the equation for $r$ !
