Answer:

+17

Step-by-step explanation:

may or may not be correct:

We have to represent earning 17. When we earn, we are adding. An integer is a positive or negative number. So +17 is an integer, and it shows we added 17.

Write a rule for the nth term of the sequence.

Helga [31]

Answer:

The rule for given sequence is: a_n = -27+16n

And the 100th term is: 1573

Step-by-step explanation:

Given sequence is:

-11, 5, 21, 37, 53, ...

Here

$a_1 = -11\\a_2 = 5\\a_3 = 21\\a_4 = 37$

First of all, we have to find if this is an arithmetic sequence

For that purpose, the common difference has to be found. Common difference, denoted by d, is the difference between consecutive terms of an arithmetic sequence

So,

$d = a_2 -a_1 = 5-(-11) = 5+11 = 16\\d = a_3 -a_2 = 21-5 = 16\\d = a_4-a_3 = 37-21 = 16$

As the common difference is same, the sequence is an arithmetic sequence

General rule for arithmetic sequence is:

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

Putting values

$a_n = -11+(n-1)(16)\\a_n = -11+16n-16\\a_n = -27+16n$

For 100th term,

Putting n=100

$a_{100} = -27+16(100)\\a_{100} = -27+1600 = 1573$

Hence,

The rule for given sequence is: a_n = -27+16n

And the 100th term is: 1573

It takes Mark 3 minutes to make 1 1/2 inches of a bracelet. If he works at the same speed, how many minutes will it take him to

RUDIKE [14]

Answer:

24 minutes

Step-by-step explanation:

Working at the same speed, the ratio of time to length is the same:

time/length = t/12 = 3/(1.5)

t = 12(3/1.5) = 12(2) = 24

It will take Mark 24 minutes to make a 12-inch bracelet.

Solve |x| > -9. No solution All reals { x | x < -9 or x > 9}

neonofarm [45]

All reals is the answer.

Since y =-9 graph is way below the absolute value graph. Meaning that y value of modulus is greater than the constant graph.
