Answer:

LK = 38

Step-by-step explanation:

MN is the midsegment, and the midsegment is the average length of the top and bottom, so:

\frac{18 + LK}{2} =28

solve for LK:

18+LK=56\\\\LK=38

Find the first 4 terms in each sequence​
koban [17]

Answer:

a₁ = -21  (Given)

a₂ = -28

a₃ = -35

a₄ = -42

Step-by-step explanation:

First term a₁ = -21  (Given)

…………………………………

Second term a₂ :

a₂ = a_{2-1} - 7\\a_{1} - 7\\a_{1} = -21\\-21 - 7 = -28

…………………………………

Third term a₃ :

a₃ = a_{3-1} - 7\\a_{2} - 7\\a_{2} = -28\\-28 - 7 = -35

…………………………………

Fourth term a₄ :

a₄ = a_{4-1} - 7\\a_{3} - 7\\a_{3} = -35\\-35 - 7 = -42

What is an equation of the line that passes through the points (4, 4) and (8, 1)?
geniusboy [140]

Answer: y = -3/4x + 7

Step-by-step explanation:

first find slope:

y2-y1 / x2 - x1

1-4 / 8-4

-3/4

now just plug the slope (m) into the equation of a line using one of the points to find the y intercept

ill use (8,1)

1 = (-3/4)(8) + b

now solve :)

1 = -6 + b

7 = b

so now plug in the slope and the y intercept into the slope intercept form to find the equation of the line

y = -3/4x + 7

The algebraic form of a sequence is 4n+1. write the sequence​
diamong [38]

Answer:

5, 9, 13, 17, 21, .....

Step-by-step explanation:

To generate the sequence, substitute n = 1, 2, 3, 4, ..... into the rule

a₁ = 4(1) + 1 = 4 + 1 = 5

a₂ = 4(2) + 1 = 8 + 1 = 9

a₃ = 4(3) + 1 = 12 + 1 = 13

a₄ = 4(4) + 1 = 16 + 1 = 17

a₅ = 4(5) + 1 = 20 + 1 = 21
