Answer:

2x+8y=20;y=2

Solution :

{x,y} = {2,2}

System of Linear Equations entered :

[1] 2x + 8y = 20

[2] y = 2

Graphic Representation of the Equations :

8y + 2x = 20 y = 2

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = 2

// Plug this in for variable y in equation [1]

[1] 2x + 8•(2) = 20

[1] 2x = 4

// Solve equation [1] for the variable x

[1] 2x = 4

[1] x = 2

// By now we know this much :

x = 2

y = 2

We are done

Solution :

{x,y} = {2,2}

Answer:

No, Monica did not correctly factor out the GCF

Step-by-step explanation:

The given expression is $12x^3+6y^2+18xy+24x$

The prime factorization of each term are:

$12x^3y=2^2\times3\times x^3\times y$

$6y^2=2\times3\times y^2$

$18xy=2\times3^2\times x\times y$

$24x=2^3\times3\times x$

The greatest common factor is the product of the least powers of the common factors.

$GCF=2\times3=6$

The greatest common factor is 6.

If we factor the GCF, we obtain:

$6(2x^3+6y^2+3xy+4)$

Therefore Monica did not correctly factor out the GCF

First you have to know how many inches are in a square cm and then the answer that you get for that first part you just multiply that by what you have but dont use a calcutor cause it wont give you the right answer because i had this before and i got it correct

1. Find the median of the following data : 1) 3,1,5,6,3,4,5 2) 3,1,5,6,3,4,5,6

juin [17]

Answer:

a ) The first step - arrange them in ascending or descending.

1,3,3,4,5,5,6

then median is to find the middle so -

the middle of this is "4" (there are odd numbers of numbers)

b) the first step- - arrange them in ascending or descending.

1,3,3,4,4,4,6,6

then median is to find the middle so -

here the middle is 4 and 4 ( there are even numbers of numbers)

so you find average -

4+4/2 = 4

these are the answers I guess.
