Step-by-step explanation:

the line is fully horizontal meaning there isn't a slope

Answer: x - x1/ x2- x1 = y -y1 / y2-y1

x - 6/ -6-6= y - 1/ -1 -1

x -6/-12 = y -1 /-2

-2(x-6) = -12 (y-1)

-2x +12 = -12y +12

12y = 2x +12-12

y= 2x/12

y= x/6

Answer:

1) -15

Step-by-step explanation:

Hi there!

In order to solve this problem, plug in -3 for all the x-values.

Your equation will become[tex]-2(-3)^2 +3.[/tex]  

Now all you have to do is solve!

[tex]-2(9) + 3[/tex]

[tex]-18 + 3[/tex]

[tex]-15[/tex]

f(-3) = -15

I hope this helped!

The explicit formula for the sequence,

aₙ = 540(1/3)ⁿ⁻¹.

And the recursive formula for the sequence,

aₙ = aₙ₋₁(1/3).

A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding terms. This ratio is regarded as one of the geometric sequence's common ratios.

Given:

540, 180, 60, 20, ...

The sequence is a geometric sequence.

First, we find the common ratio.

180/540 = 1/3

60/180 = 1/3

20/60 = 1/3

Hence, 1/3 is the common ratio

r = 1/3

So,

the explicit formula for the sequence,

aₙ = 540(1/3)ⁿ⁻¹.

And the recursive formula for the sequence,

aₙ = aₙ₋₁(1/3)

Therefore, the formulae are given above.

Answer:

x=7

Step-by-step explanation:

Step #1- Set the two lines equal to each other

10+12=x+15

Step #2- Solve for the line you have all values for

10+12=22

Step#3- Plug 22 back into the equation where the two lines are set equal to each other

22=x+15

Step #4- Solve for X algebraically

22=x+15

Answer:

-1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−4(y−2)=12

(−4)(y)+(−4)(−2)=12(Distribute)

−4y+8=12

Step 2: Subtract 8 from both sides.

−4y+8−8=12−8

−4y=4

Step 3: Divide both sides by -4.
