I assume you mean y-coordinate because the x-coordinate would be 10 when x=10, so you substitute x=10 and get y=26

Three consecutive integers have a sum of 87. Find the integers.

elena-s [515]

Answer:

28, 29, and 30

Step-by-step explanation:

There's probably better ways but you can estimate by knowing 30*3=90 so it should be somewhere pretty close to 30. Guess and check with basic calculations to get 28, 29, and 30.

Define a sequence by a1=3 and an=3an−1. Find the first four terms of the sequence. Give a simplified integer answer.

aalyn [17]

Answer:

The first four terms are 3,9,27,81

Step-by-step explanation:

Step :-1

Given first term of sequence is $a_{1} = 3$

Given 'n' t h term is $a_{n} = 3 a_{n-1}$ .............(1)

here we put n = 2 in equation (1)

$a_{2} = 3a_{2-1}$

$a_{2} = 3 a_{1}$ ..............2

put $a_{1} = 3$ in equation (2)

$a_{2} = 3(3)$

$a_{2} = 9$

put n=3 in equation (1)

$a_{3} = 3 a_{3-1}$

$a_{3} = 3a_{2}$

$a_{3} = 3 (9) = 27$

put n= 4 in equation (1)

$a_{4} = 3 a_{4-1}$

$a_{4} = 3 a_{3}$

$a_{4} = 3(27) = 81$

The first four terms of the sequence is

3 , 9, 27 , 81 ....this is geometric sequence

a =3 and ratio term is r =3

Tania is riding a train for $43.6$ miles to get to her destination. The train has $14.3$ more miles to travel before arriving at

Gala2k [10]

Answer:

A )

m +14.3 =43.6

m =29.3

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Miles to travel: 43.6
Miles left to travel: 14.3

To find the amount of miles that the train has already traveled (m), we know that the sum of that value (m) and the miles left to travel (14.3) is equal to the total miles (43.6)

Mathematically speaking:

m +14.3 = 43.6

Solving:

m = 43.6-14.3= 29.9

The correct option is A.
