Step-by-step explanation:

3/8 and 11/15

LCM = 30

3/8x4 and 11/15x2

12/30 and 22/30

22/30-12/30

=10/30

The difference is 10/30

The larger sum is 11/15

9. What statements are NOT true about the solution of the system?

Crazy boy [7]

Answer:

A, B, C, and E

Step-by-step explanation:

y = 4x - 20

8x - 2y = - 20 (divide everything by 2)

4x - y = -10

-y = -4x - 10

y = 4x - 10

4x - 10 = 4x - 20

0 $\neq$ -10

No solution

The arithmetic sequence a_ia i a, start subscript, i, end subscript is defined by the formula: a_1 = 15a 1 =15a, start subsc

daser333 [38]

Answer:

-1,512,390

Step-by-step explanation:

Given

a1 = 15

$a_i = a_{i-1} -7$

Let us generate the first three terms of the sequence

$a_2 = a_{2-1}-7\\a_2 = a_1 - 7\\a_2 = 15-7\\a_2 = 8$

For $a_3$

$a_3 = a_{3-1}-7\\a_3 = a_2 - 7\\a_3 = 8-7\\a_3 = 1$

Hence the first three terms ae 15, 8, 1...

This sequence forms an arithmetic progression with;

first term a = 15

common difference d = 8 - 15 = - -8 = -7

n is the number of terms = 660 (since we are looking for the sum of the first 660 terms)

Using the formula;

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

Substitute the given values;

$S_{660} = \frac{660}{2}[2(15) + (660-1)(-7)]\\S_{660} = 330[30 + (659)(-7)]\\S_{660} = 330[30 -4613]\\S_{660} = 330[-4583]\\S_{660} = -1,512,390$

Hence the sum of the first 660 terms of the sequence is -1,512,390
