Domain - {0, 1, 2, 3}

Range - {2, 5, 8, 11}

The domain is x and the range is y

Hope that helped:)

190 = 6n - 2(-8n - 7)

andrew11 [14]

Answer:

n=8

First you remove the parentheses making it 190=6n+16n+14
Then you combine like terms making it 190=22n+14
After that, you move the terms making it -22n=14-190
After that, you calculate and that gives you -22n=-176
Lastly, you divide both sides leaving you with n=8

0, -1 I think. If that’s wrong use a calculator and take the answer and subtract it by the answer of the first problem

(-10) - |(-20) – (+30) |

myrzilka [38]

ANSWER: -60

EXPLANATION: To solve for (-10) - |(-20) – (+30) |, we need to do:

−10−| −20 − 30|, which equals −10−|−50|. Next, we do −10−50, which is -60.

−10−|−20−30|

= −10−|−50|

= −10−50

= −60

Answer:

Sum of 100 terms of the sequence = 15050

Step-by-step explanation:

Given expression which represents a sequence is,

$\sum_{r=1}^{100}(3r-1)$

So the sequence will be,

2, 5, 8, 11, 14..........

So, the given sequence is an arithmetic sequence with,

First term of the sequence 'a' = 2

Common difference 'd' = 5 - 2 = 3

Sum of 'n' terms of an arithmetic sequence is given by,

$S_n=\frac{n}{2}[2a+(n-1)d]$

Here, n = number of terms

a = first term

d = common difference

$S_{100}$ = $\frac{100}{2}[2(2)+(100-1)(3)]$

= 50[4 + 297]

= 15050

Therefore, sum of 100 terms of the sequence = 15050
