To factor, you do the opposite of what you would in distributive property. You have to find the greatest common factor, or GCF, of 4 and -2.

4 2

------ -------

1 | 4 1 | 2

2 | 2

So the GCF is 2. Now we factor the expression.

4x-2

2(2x-1)

Solve the following system algerbraically: y=-3(x-2) squared+4 y=-6x+16

pishuonlain [190]

$y = - 3(x - 2) ^{2} + 4$
$y = - 6x + 16$
distribute the -3 and the square into the first equation
$y = - 3x ^{2} + 12x - 8$
$y = - 6x + 16$
multiply the second equation by 2
$y = - 3x ^{2} + 12x - 8$
$y = - 12x + 32$
add the equations together
$y = - 3x ^{2} + 24$
factor out -3
$y = - 3(x ^{2} - 8)$
factor inside parenthesis
$y = - 3(x + \sqrt{8} )( x - \sqrt{8})$
refine
$y = - 3(x + 2 \sqrt{2} )(x - 2 \sqrt{2} )$

The formula for the nth term of the arithmetic sequence first term is 9 common difference is -2

Yanka [14]

Answer:

$a_n = 9 - 2(n-1)$

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms is always the same, and is called common difference.

The nth term is given by the following equation:

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

In which $a_1$ is the first term and d is the common difference.

First term is 9 common difference is -2

This means that $a_1 = 9, d = -2$

So, the nth term is given by:

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

$a_n = 9 + (n-1)(-2)$

$a_n = 9 - 2(n-1)$

Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10

n200080 [17]

Answer:

(0,2)

Step-by-step explanation:

solve by addition/elimination

2x + 3y= 6

–3x + 5y = 10

multiply first equation by 3 and second one by 2 to eliminate x)

6x+9y=18

-6x+10y=20 (add the two equations)

6x+9y-6x+10y=38

19y=38

y=38/19=2

2x+3y=6

2x=6-6

x=0
