simplify this expression: 11k - 3 + 4k + 8

Answer:

.75 or 3/4

Step-by-step explanation:

Answers

A 3

B t = -7n +39

C 51.571

It is declining!

32 to 25 decreases by 7

25 to 18 decreases by 7

18 to 11 decreses by 7

The sequence is linear!

39 is the 0th term and our numbers are decreasing by 7 each term.

t = -7n +39 is our equation

a) -7(6) + 39

-49 + 39

3

b) to find nth term replace the term with n in this equation:

t = -7n +39

c) -332 = -7n +39

Subtract 39 from both sides!

-361 = -7n

Divide both sides by -7!

n = 51.571

The 6th term will be equal to -3, the nth term of the sequence will be equal to -7n + 39 and the term will be the 53rd term.

Two definitions are given for an arithmetic sequence. A "series where the variances in between every two succeeding terms are the same" is what it is.

Each term in an algebraic expression is created by multiplying its previous term by a specified integer (either positive, negative, or zero).

As per the given information in the question,

The sequence is given as:

32, 25, 18, 11, 4

(a)

a = 32

d = 25 - 32 = -7

n = 6

Then,

a₆ = a + (n - 1)d

a₆ = 32 + (6 - 1)(-7)

= 32 - 35

= -3

(b)

Find the nth term.

[tex]a_n[/tex] = a + (n - 1)d

= 32 + (n - 1)(-7)

= 32 -7n + 7

[tex]a_n[/tex] = -7n + 39

(c)

-332 = 32 + (n - 1)(-7)

-332 - 32 -7 = -7n

n = -371/-7

n = 53rd term.

Answer:

d. skewed to the right with possible outliers

Step-by-step explanation:

The distribution of house prices will be skewed to the right with possible outliers. This is because the regular median prices are still fairly far apart from each other with roughly $300,000 in difference between them. Also since there are some extreme house prices also included that greatly surpass the normal range these would be considered outliers in the data set.

Answer:a

Step-by-step explanation:

The equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

This is the required equation of a line in a point-slope form.

We know that Point-Slope Form:

y - y₁ = m(x- x₁)  

Where x₁ - x coordinate and y₁ - y coordinate

m - slope

Point (8,-4)

Then Slope m = 1/2

Now the equation as;

y + 4 = 1/2(x - 8)

 y  = -1/2(x -4) - 4

y = -x/2 + 2 - 4

y = -x/2 - 2

Hence, the equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

Step-by-step explanation:

All the numbers have to be multiplied by the same amount for it to be proportional

A proportional amount to 4:2:1:5 would be 12:6:3:15

They have all been multiplied by the same number 3

Answer:

Yes, the ratio is proportional

Step-by-step explanation:

given 4.2 : 1.5 =? 12.6 : 4.5 is it proportional

it must follow the means extremes property

[tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex]

a*d = b*c, so let's plug in the values

[tex]\frac{4.2}{1.5}[/tex] =? [tex]\frac{12.4}{4.5}[/tex]

(4.2)*(4.5) =? (1.5)*(12.6)

18.9 = 18.9 which is true; therefore the ratio is proportional

Step-by-step explanation:

i did this in my head, but the difference between -8 and 7 is 15. the difference between 2 and 7 is 5. it's rise over run so (15,5). that simplified is (3,1)/3. that is the slope. now you need a graph to see the y-int. the y-int is around 4.5.
