j=2

Step-by-step explanation:

take the second numbers in each parentheses and subtract them. put this answer on top of a fraction

(j,3) (8,2)

2-3 = -1

take the first numbers and subtract. put this answer at the bottom of fraction

8 - J = 6

j = 2

answer should equal -1/6

the formula for a slope is y2-y1/x2-x1

look at the points like this, and fill in the places with the numbers and j they give you

(X1,y1) (X2,y2)

Use the like bases property to solve the equation:<br> 16^x = 1/4<br> x=

gavmur [86]

Answer:-1/2

Step-by-step explanation:

16^x=1/4

(4^2)^x=4^(-1)

4^2x=4^(-1)

Base cancelled each other since they are the same

2x=-1

Divide both sides by 2

2x/2=-1/2

x=-1/2

What is the 38th term of 459,450,441,..

galina1969 [7]

Answer:

The 38th term of 459,450,441,.. will be:

$a_{13}=351$

Step-by-step explanation:

Given the sequence

$459,450,441,..$

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$450-459=-9,\:\quad \:441-450=-9$

$d=-9$

The first element of the sequence is

$a_1=459$

so the nth term will be

$a_n=-9\left(n-1\right)+459$

$a_n=-9n+468$

Putting n=38 to find the 38th term

$a_n=-9n+468$

$a_{13}=-9\left(13\right)+468$

$a_{13}=-117+468$

$a_{13}=351$

Therefore, the 38th term of 459,450,441,.. will be:

$a_{13}=351$

22 - [1/2 • (5 x 4) + 4]

Montano1993 [528]

8 because you do the multiplication which is 20 and multiply 20 by 1/2 which is 10 then add 4 which is 14. then 22-14 is 8.
