Find the xx-intercept of each line defined below and compare their values.

alexandr1967 [171]

Answer:

$\displaystyle greater\:than \\ Line\:B: [-6, 0] \\ Line\:A: [2, 0]$

Step-by-step explanation:

The x-intercept of Line B is already given to you because it is where the graph intersects the x-axis.

Now, to get the x-intercept of Line A, plug 0 in for y to get this:

0 = −2x + 4

- 4 - 4

_____________

$\displaystyle \frac{-4}{-2} = \frac{-2x}{-2} \\ \\ 2 = x$

So, the x-intercept of Line A is $\displaystyle [2, 0],$ and since 2 is greater than −6, greater than would be your answer.

What is the sum of the series 3,---5,-13..........-229

Tpy6a [65]

ANSWER

$S_{30}= - 3390$

EXPLANATION

The given sequence is

3,-5,-13,.....-229.

The first term of this sequence is

a_1=3

There is a common difference of

$d = - 5 - 3 = - 8$

The last term of this sequence is -229.

The nth term of this sequence is given by:

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

We use the last term to determine the number of terms in the sequence.

$- 229 = 3 + - 8(n - 1)$

$- 229 - 3= - 8(n - 1)$

$- 232= - 8(n - 1)$

Divide through by -8;

$29= (n - 1)$

$n = 30$

Hence there are thirty terms in the sequence.

The sum of the first n terms is given by:

$S_n= \frac{n}{2} ( a_{1} + l)$

The sum of the first 30 terms is given by:

$S_{30}= \frac{30}{2} ( 3 + - 229)$

$S_{30}=15( - 226)$

$S_{30}= - 3390$

Will rounding to the nearest 10 0r 100 give a closer estimate of 748-431?

pav-90 [236]

Answer:

If it's all five then just round to the bigger ten , hundred or thousand. like if it's five then rounded to the nearest ten would be 10 .if it's 55 rounded to the nearest hundred is 100. if the number is 555 rounded to the nearest thousand is one thousand. remember if it's five or more round it to the bigger ten, hundred or thousand. if it's 4 or smaller then round it to the smaller ten ,hundred or thousand.

I HOPE IT CAN HELP:)
