What is the solution for the following system of equations? Use ANY method to solve. 2x + 8y = 4 x = -3y + 5 Question 4 options: x = 14, y= -3 x = 2, y = -3 x = -3, y = -3 x = 12, y = 5

Answers

Answer:

x = 14, y= -3

Step-by-step explanation:

Solve the following system:

{2 x + 8 y = 4 | (equation 1)

{x = 5 - 3 y | (equation 2)

Express the system in standard form:

{2 x + 8 y = 4 | (equation 1)

{x + 3 y = 5 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:

{2 x + 8 y = 4 | (equation 1)

{0 x - y = 3 | (equation 2)

Divide equation 1 by 2:

{x + 4 y = 2 | (equation 1)

{0 x - y = 3 | (equation 2)

Multiply equation 2 by -1:

{x + 4 y = 2 | (equation 1)

{0 x+y = -3 | (equation 2)

Subtract 4 × (equation 2) from equation 1:

{x+0 y = 14 | (equation 1)

{0 x+y = -3 | (equation 2)

Collect results:

Answer: x = 14, y = -3

What are the three consecutive odd integers that equal 111? After that, answer this:Are there 3 consecutive odd integers that equal 1111?

Answers

odd integers are 1 more than even ones
even intergers are represetned as 2n where n is a whole number
odd=2n+1
consecutive odd integers are 2 apart from each other so therefor the numbers are 2n+1,2n+1+2, 2n+1+2+2 or 2n+1, 2n+3, 2n+5
so they add up to 111
2n+1+2n+3+2n+5=111
add like terms
6n+9=111
subtract 9 from both sides
6n=102
divide both sides by 6
n=17
numbers are
2n+1,2n+3,2n+5
subsitute
2(17)+1=34+1=35
therefor since the other sare 2 more
35,37,39 are the numbers

are there 3 that equal 1111? solve and see if it is true
2n+1+2n+3+2n+5=1111
add like terms
6n+9=1111
subtract 9 from both sides
6n=1102
divide both sides by 6
n=183.666666666666
n is not whole so the answer is NO

answer are 35,37,39 and NO

x- the number

x
x+2
x+4
======(+)
3x+6=111
3x=105
x=35

the numbers are 35 37 39

the second problem has the same logic

x
x+2
x+4
=====(+)
3x+6=1111
3x=1105
x=368, (3) it's not an integer number

Alissa cut a pices of string that was 17 feet long.Darnell cut piece of string that was 5 yard long Alissa wanted to cut her string so that it was the same length as Darnell's how many feet did she need to cut.

so alissa has 17 feet
darnel has 5 yards
1 yard=3 feet
5 yard times 3=15 feet
17 feet-x=15
add x to both sides
17=15+x
subtract 15
2=x
she needs to cut 2 feet

Answer: 2 feet
