So -h+4= -h + 9 so -2h + 4 = 9 so -2h = 5 so -h= 2.5 so h = -2.5. Hope this helps :)

Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. 125, 25

Igoryamba

Answer:

Given sequence is an arithmetic sequence.

Step-by-step explanation:

Given sequence is:

125, 25, 5, .. ..

Here

$a_1 = 125\\a_2 = 25\\a_3 = 5$

A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.

A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.

Finding the common ratio

$r = \frac{a_2}{a_1} = \frac{125}{25} = 5\\r = \frac{a_3}{a_2} = \frac{25}{5} = 5$

As we can see that the common ratio is same, the given sequence is a geometric sequence.

Find the explicit formula for a 1 =-4,a n =a n-1 +9,n>=2

Mrrafil [7]

Given:

$a_1=-4$ and $a_n=a_{n-1}+9$ where $n\geq 2$ .

To find:

The explicit formula for the given recursive formula.

Solution:

We know that recursive formula of an AP is:

$a_n=a_{n-1}+d$

Where, d is the common difference.

We have,

$a_n=a_{n-1}+9$

Here, d=9.

The first term of the AP is $a_1=-4$ .

The explicit formula for an AP is:

$a_n=a_1+(n-1)d$

Substituting $a_1=-4$ and $d=9$ , we get

$a_n=-4+(n-1)9$

$a_n=-4+9n-9$

$a_n=-13+9n$

Therefore, the required explicit formula for the given sequence is $a_n=-13+9n$ .

Examine this system of equations. Which number can be multiplied by each equation so that when the two equations are

andreyandreev [35.5K]

Answer:

15 times the first equation and -12 times the second equation

Step-by-step explanation:

we have

$\frac{3}{4}x+\frac{2}{3}y=6$ ------> first equation

$\frac{5}{8}x+\frac{5}{6}y=12$ ------> second equation

Multiply the first equation by 15 both sides

$(15)\frac{3}{4}x+(15)\frac{2}{3}y=6(15)$

$\frac{45}{4}x+10y=90$ -----> new first equation

Multiply the second equation by -12 both sides

$(-12)\frac{5}{8}x+(-12)\frac{5}{6}y=12(-12)$

$-\frac{60}{8}x-10y=-144$ -----> new second equation

Adds the two new equations

$\frac{45}{4}x+10y=90\\-\frac{60}{8}x-10y=-144\\-----------\\\frac{45}{4}x-\frac{60}{8}x=90-144$

The y-term was eliminated
