Christopher is 20 years younger than Ishaan. Ishaan and Christopher first met two years ago. Fourteen years ago, Ishaan was 3 times as old as Christopher.
How old is Christopher now?

Answers

Answer 1

Answer: Yw :^

Step-by-step explanation: Present: Ishaan = Christopher + 20       - Equation 1

1 years back: Ishaan-14 = 3(Christopher-14)    - Equation 2

 

Solve above equations:

 

I = 3c-42+14

I = 3c-24

I = c+20

 

2c-44 = 0

 

Christopher = 22  then from Equation 1

Ishaan = 22 + 20 = 42

Show work to receive full credit

Answers

Answer:

(3x - y)(x + y)²

Step-by-step explanation:

3x³ - x²y + 6x²y - 2xy² + 3xy² - y³ =x²(3x - y) + 2xy(3x - y) + y²(3x - y) =(3x - y)(x² + 2xy + y²) = (3x - y)(x + y)²

Answer:

[tex](3x-y)(x+y)^2[/tex]

Step-by-step explanation:

[tex]3x^3-x^2y+6x^2y-2xy^2+3xy^2-y^3[/tex]

Multiply and combine like terms.

[tex]3x^3+xy^2-y^3+5xy^3[/tex]

Consider [tex]3x^3+xy^2-y^3+5xy^3[/tex] as a polynomial over variable x.

[tex]3x^3+5xy^2+y^2x-y^3[/tex]

Find one factor of the form kx^m +n, where kx^m  divides the monomial with the highest power 3x^3  and n divides the constant factor −y^3 . One such factor is 3x−y. Factor the polynomial by dividing it by this factor.

[tex](3x-y)(x^2+2xy+y^2)[/tex]

Consider [tex]x^2+2xy+y^2[/tex]. Use the perfect square formula, [tex]a^2+2ab+b^2[/tex] = [tex](a+b)^2[/tex], where a=x and b=y.

[tex](x+y)^2[/tex]

Rewrite the complete factored expression.

4x + 3 = x + 2(x + 7)
step by step

Answers

Answer:

x=11

Step-by-step explanation:

4x + 3 = x+ 2x + 14

4x + 3 = 3 x + 14

4x - 3x = 14 -3

x= 14 - 3

x= 11

Answer:

x=11

Step-by-step explanation:

Distribute :

4x + 3 = x + 2( x+ 7)

4x + 3 = x + 2x + 14

Combine like terms :

4x + 3 = x + 2x + 14

4x + 3 = 3 x+ 14

Subtract 3 from both sides of the equation :

4x + 3 = 3x + 14

4x + 3-3 = 3x + 14 -3

Simplify :

what ever way you know how to subtract the numbers you should get this answer :

4x = 3x + 11

Subtract 3 from both sides of the equation :

4x = 3x + 11

4x - 3x = 3x + 11 - 3x

Simplify :

combine like terms

multiply by 1

combine like terms

x= 11

if an is defined as a geometric sequence, is the sequence 1/an also a geometric sequence? explain your reasoning.​

Answers

Answer:

Since An/An-1 = r

(1/An)/(1/An-1) = An-1/An = 1/r

so, the ratio between terms is still constant.

Step-by-step explanation:

If an is defined as a geometric sequence, is the sequence 1/an also a

geometric sequence because the ratio between terms remain constant.

What is a geometric sequence and how to find its nth terms?

Suppose the initial term of a geometric sequence is a and the term by which we multiply the previous term to get the next term is r

Then the sequence would look like

[tex]a, ar, ar^2, ar^3, \cdots[/tex]

 (till the terms to which it is defined)

Thus, the nth term of such sequence would be[tex]T_n = ar^{n-1}[/tex]

Since An/An-1 = r

(1/An)/(1/An-1) = An-1/An = 1/r

Therefore, the ratio between terms is still constant.

Which set of integers is ordered from least to greatest -13 , 4, 0, -8 -5 , -2, 3, 1 -12 , -18 , -4 , 7 -15, 6 , -9 , -21

Answers

Given:

The set of integers in the options.

-13 , 4, 0, -8

-5 , -2, 3, 1

-12 -18 , -4 , 7

-15, 6 , -9 , -21

To find:

The set of integers that is ordered from least to greatest.

Solution:

We know that the larger negative value is the smaller value and the larger positive value is the greater value.

Ordered from least to greatest means first we need to write the smallest value, write the value larger than and the greatest value occurs at the end.

In option A, we have -13 , 4, 0, -8. Here, 4>0. So, the option A is incorrect.

In option B, we have -5 , -2, 3, 1. Here, 3>1. So, the option B is incorrect.

In option C, we have -12 -18 , -4 , 7 Here, -12>-18. So, the option C is incorrect.

In option D, we have -15, 6 , -9 , -21. Here, 6>-9. So, the option D is incorrect.

Therefore, all the options are incorrect.

Solve the system of equations by substitution.
3x+2y=10 y=3x-4
x= y=​

Answers

Answer:

x=2;  y=2

Step-by-step explanation:

3x+2y=10

y=3x-4

We can substitute y from the first equation with the second equation:

3x+2(3x-4)=10

3x+6x-8=10

9x=18

x=2

Now plug this in to any of the equations (i used second equation):

y=3(2)-4

y=6-4

y=2

Check your answers:

y=3x-4

2=3(2)-4

2=6-4
