Lostsunrise [7]3 years ago
4 0

Answer:

2y^3 + 2y^2 - y - 1

Step-by-step explanation:

6у^5 + 4y^4 - 3у^3-1 by  y^2 - y + 1:-

We need to write the first expression as

бу^5 + 4y^4 - 3у^3 + 0y^2 + 0y  - 1  (inserting all the missing degrees).

So we have:

3y^2 - y + 1​  ) бу^5 + 4y^4 - 3у^3 + 0y^2 + 0y  - 1 ( 2y^3 + 2y^2 - y - 1

                     6y^5  - 2y^4 + 2y^3

                                 6y^4  - 5y^3  + 0y^2

                                 6y^4 - 2y^3  + 2y^2

                                           -3y^3   - 3y^2 + 0y

                                            -3y^3   + y^2  -  y

                                                          - 3y^2 + y  -  1

                                                          - 3y^2  + y -  1

                                                          .........................

What is the 4th term of the linear sequence below?<br> -9,-5, -1,3,7,...
Anton [14]

Answer:

The 4th term of the linear sequence = 3

Step-by-step explanation:

First term, a = -9

Common difference, d = -5 - (-9)

= -5 + 9

= 4

d = 4

The 4th term of the linear sequence = a + (n - 1)d

where,

n = 4

a + (n - 1)d

= -9 + (4 - 1)4

= -9 + (3)4

= -9 + 12

= 3

The 4th term of the linear sequence = 3

The sum of three consecutive odd numbers is 123 what is the smallest of the three numbers
Inga [223]

Answer:

39

Step-by-step explanation:

Let the three consecutive odd numbers be:

x+2, x+4, x+6.

The sum of the consecutive numbers is 123 i.e

x+2 + (x+4) + (x+6) = 123

x + 2 + x + 4 + x + 6 = 123

3x + 12 = 123

Collect like terms

3x = 123 — 12

3x = 111

Divide both side by the coefficient of x i.e 3

x = 111/3

x = 37

Now let us find the value of the three odd numbers. This is illustrated:

1st : x + 2 = 37 + 2 = 39

2nd : x + 4 = 37 + 4 = 41

3rd : x + 6 = 37 + 6 = 43

The smallest of the three consecutive odd numbers is 39

Problem #2
marta [7]

Fractions can be converted to decimals and vice versa.

<em>The decimal equivalent  of the fraction of months with 31 days is 0.583</em>

Given:

<em />Total = 12<em> --- months in a year</em>

<em />Months = 7<em> --- months with 31 days</em>

<em />

The fraction (n) of months with 31 days is:

n = \frac{Months}{Total}

So, we have:

n = \frac{7}{12}

The decimal equivalent is:

n = 0.583

Hence, (c) is correct.
