line w passes through point (-6,-7) and has a slope 1/2. what is the equation for the line in point-slope form?

Answer:

k =1

Step-by-step explanation:

3x + y = -7

      y = -3x - 7

m = -3

Parallel lines have same slope

[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]

Cross multiply,

9 = -3(-2-k)

9 = 6 + 3k

9-6 = 3k

3 = 3k

3/3 = k

k = 1

Answer:

26/35

Step-by-step explanation:

1. First to divide the 3 1/2 by 2 3/5 you have to turn them both into improper fractions

First take 3 1/2. You have to multiply the whole number (3) by the denominator (2) and you would get 6. Then you would add then you add the product (6) to the numerator (1) and get 7.

You keep the denominator the same so the improper fraction is 7/2

Do the same thing to 2 3/5 and the improper fraction is 13/5

2. Now we can divide 13/5 by 7/2 using "keep, change, flip"

Keep: 13/5

Change: division to multiplcation

Flip: 7/2 to make 2/7

Your new equation is 13/5 × 2/7. Multiplcation is easy so you just have to multiply staight across: 13 × 2 and 5 × 7 giving you 26/35

If you divide 35 by 26 you will get 1.34 and a bunch of other numbers but I usually stop at two decimal places

hope this helps :)

First term: 3

Exiplicit formula:

[tex]3/5*5^n[/tex] or 3x5^n-1

Hope this helps!

The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex].

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

As per the given GP series,

3,15,75,375, 1,875​

The common ratio r = 15/3 = 5

First term a = 3

The nth term is given as a[tex]r^{n-1}[/tex]

Therefore,

The nth term will be as, 3 × [tex]5^{n-1}[/tex]..

Hence "The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex]".

Answer: 15 7/8

Step-by-step explanation:

Add the whole numbers first 6+9 to getting 15

Now find the lowest common denominator for both the fractions. In this case it is 8.

3/8 would stay the same however 1/2 would become 4/8. 4/8 + 3/8 is 7/8.

15 add 7/8 is 15 7/8

Step-by-step explanation:

devide both sides on 3 and x=6

as u can see 3*6=18

u have to find a number hat when its multiplied on 3 equals 18

so x(the number were searching for) is 6

Answer:

x = 6

Step-by-step explanation:

1. Divide Both Sides By The Coefficient

18/3 = 3x/3

6 = x

2. Move the variable to the Left

x = 6

Topic: Mathematics 8, Pre-Algebraic Skills

Answer: The slope should be 2/3

Step-by-step explanation: Slope is rise over run. Remember you always rise before you run. So in this case you start at the origin and go up until you get to the point on the line where the line is centered. You go up 3 times and thats where the first actual point is. Then move to the side until you get to the line which is 2 to the right. so therefore your answer is 3/2

The number in the question that gives 28 after the operations is; 3

We are told that the product of seven and the sum of a number and 1 is 28.

Let the number be x. Thus;

7(x + 1) = 28

Use division property of equality to divide both sides by 7.

7(x + 1)/7 = 28/7

(x + 1) = 4

Use subtraction property of equality to subtract 1 from both sides to get;

x + 1 - 1 = 4 - 1

x = 3

Therefore, in conclusion the number is 3.

(1/3)^4 = 1^4/ 3^4 = 1/81

Answer: 1/81

The expression 1/3 by the power of 4  when evaluated has a value of 1/81

From the question, we have the following parameters that can be used in our computation:

1/3 by the power of 4

Express as an equation

So, we have

1/3 by the power of 4 = 1/3⁴

When expanded, we have

1/3 by the power of 4 = 1/3 * 1/3 * 1/3 * 1/3

Evaluate the products

This gives

1/3 by the power of 4 = 1/81

Hence, the solution is 1/81

Step-by-step explanation:

Answer:

I can't read that...........

Answer:

A  8º

B  76º

C  74º

D  128º

Step-by-step explanation:

The sum of the angles is 360

(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360

Combine like terms

12x + 72 = 360

Subtract 72 from both sides

12x = 288

Divide both sides by 12

x = 24

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

A (3x+10) = 3*24 + 10 = 82

B (3x+4) = 3*24 + 4 = 76

C (x+50) =  24 + 50 = 74

D (5x+8) = 5*24 + 8 = 128

Answer:

A) No solution

Step-by-step explanation:

Given the systems of linear equations, y = 2x + 1 and y = 2x - 1:

Both equations in the system have the same slope, m = 2, thus forming parallel lines.  Since their lines are parallel from each other, then it means that their lines will never intersect.

Therefore, the given systems of linear equation is an inconsistent system that has no solution.
