Hey there!!

Formula - y = mx + b

Where m = slope

Equation given : 2x + 4y = 12

...2x + 4y = 12

...4y = 12 - 2x

... y = 12 - 2x / 4

... y = 12 / 4 - 2x/4

... y = 3 - x / 2

... y = -x/2 + 3

Hence, the slope is -1/2

Hope my answer helps!!

Hello!

To find the slope of the given equation, we would need to convert this equation from standard form into slope-intercept form. Our goal, is to get the variable y, on one side of the equation.

Remember that slope-intercept form is written as y = mx + b. In this form, m is the slope and b is the y-intercept.

2x + 4y = 12 (subtract 2x from both sides)

4y = 12 - 2x (divide both sides by 4)

y = 12/4 - 2/4x → y = -1/2x + 3

Therefore, the slope of this equation is -1/2, which is the final choice listed.

What is 6 to the 6 power
Lady bird [3.3K]

Answer:

6 to the sixth power is 46,656.

Step-by-step explanation:

I know this because you have to multiply 6 by itself six times to get your answer.

Step by step:

6×6=36

36×6=216

216×6=1,296

1,296×6=7,776

7,776×6=46,656

46,656 is your answer

Equation: 6×6×6×6×6×6= 46,656

Enter a recursive rule for the geometric sequence. 10, −80, 640, −5120, ...<br><br> a(1)=<br> a(n)=
Liula [17]
The recursive formula would be:
a_1=10&#10;\\a_{n}=a_{n-1} \times (-8)

This is because the first term, a₁, is 10.  A recursive rule is dependent upon the term before it (a(n-1)) and the common ratio.  The common ratio, or the number that each term is multiplied by, is -8.
