Answer:

Step-by-step explanation:

4f-3 = 5f-6

First I would try to get the f's on one side and the other numbers on the other, to do this you woudl have to add 6 to both sides

4f -3 = 5f -6

+6 +6

Making it into: 4f + 3 = 5f

Now to get the 4f on the other side we will have to subtract it from both sides

4f +3 = 5f

-4f -4f

3= f (Remember you do not have to put the 1, making 3 your answer)

J. Reexamine the sequence 20, 14, 8, 2, ... from the problem

DENIUS [597]

Answer:

The n th of the given sequence is $t_{n} = 26-6 n$

Step-by-step explanation:

Step 1 :-

Given sequence is 20,14,8,2,.......this sequence in arithmetic progression but this sequence is decreasing sequence.

given first term is 20 and difference is $d = second term- first term = 14-20=-6$

now the nth term of given sequence is

by using formula $t_{n}=a+(n-1)d$

$t_{n}= 20+(n-1)(-6)$

$t_{n}= 20-6 n+6$

final answer:-

$t_{n} = 26-6 n$

verification:-

$t_{n} = 26-6 n$

put n=1 we get first term is 20

put n=2 we get second term is 14

put n=3 we get third term is 8

put n=4 we get fourth term is 2

so the n th term of sequence is

$t_{n} = 26-6 n$

She needs to earn at least 84 to buy the mp3 player

earnings=earningsperhour times numberofhoursworked

earnings per hour=12 dollars
number of hoursworked=h

therefor
earnings=12 ties h or12h

earnings is at least 84
earnings is greater than or equal to 84
earnings>84
12h>84

solve
12h>84
divide both sides by 12
h>7
she needs to work at least 7 hours

to graph, draw a line at x=0 and shade to the right, make the line solid
