Answer:

1.) x = -3 2.) x = 4/3 3.) x = 698/77 or 9.1

Step-by-step explanation:

1.) 4 + 2x = -2

2x = -2 - 4

2x = -6

x = -3

2.) -1 (3x - 12) = 9x - 4

-(3x - 12) = 9x - 4

-3x + 12 = 9x - 4

-3x - 9x = -4 - 12

-12x = -16

x = 4/3

3.) x - 4 = 13 (6x - 54)

x - 4 = 78x - 702

x - 78x = -702 + 4

-77x = -698

x = 698/77 or 9.1

Answer:

1. x = -3

2. x = 4/3

3. x = 698/77

Step-by-step explanation:

4+2x=-2

-4       -4

2x= -6

/2     /2

x=-3

You have to get x alone on one side. Search up on yt "How to solve for x on two sides."

Write a rule for the nth term of the arithmetic sequence. Then graph the first six terms of the sequence. a6=-12 a12=-36
denis-greek [22]

Answer:

We need to find the first term.  We can use the formula

an = a1 + d(n - 1)

to solve for a1.  We already know the 12th term, a12, common difference, d, and nth sequence, n.

a12 = -36

d = -4

n = 12

-36 = a1 - 4(12 - 1)

-36 = a1 - 44

8 = a1

The first term is 8.  Therefore, your formula is

an = 8 - 4(n - 1)

an = -4n + 12

Then use this formula to graph.

n is the independent variable.

an is the dependent variable.

Your graph will be a line.

n    |       an

___________

1          8

2          4

3          0

4         -4

5         -8

6         -12

What is the equation of the line that is perpendicular to 3x -6y =2 and contains the point (-2,--5)​
julsineya [31]

Answer:

y=-2x-12

Step-by-step explanation:

first, putt 3x-6y=2 in standard form:

subtract 3x from both sides: -6y=-3x+2

divide both sides by -6 to isolate y: y=1/2x-1/3

if the other line is perpendicular to this, you must find the slope by finding the opposite reciprocal of 1/2x: -2

now we have 2 points a slope, so we use the point-slope formula: y-y1=m(x-x1)

y+2=-2(x+5)

Use the distributive property: y+2=-2x-10

subtract 2 for both sides to isolate y: y=-2x-12

In a package of candy there is a total of 24 yellow pieces. For every 5 green pieces in the package, there are 8 yellow pieces.
IgorLugansk [536]

Answer:

15 green pieces.

Step-by-step explanation:

8x = 24

x = 3.

So you need 3 times the amount of green pieces for every yellow piece.

3 * 5 green pieces = 15 green pieces

In most places, it is only possible to see 2,000 stars in the nighttime sky due to light pollution. This is 4/15 as many stars a
emmainna [20.7K]

Let the no. of stars one can expect to see at Bryce Canyon be x.

Given that : No. of stars visible in the night sky = 2000

Also, given that, it is 4/15 of x.

Now, we have

\frac{4}{15}x = 2000\\\\x= \frac{2000 * 15}{4} = 7500

∴  You can expect to see 7,500 stars at Bryce Canyon.
