If you get 4=4 when solving a system of equations algebraically, it means there is no solution

Answer:

  C) never

Step-by-step explanation:

It means the system of equations is true for all values of the variables that satisfy one of the equations. The other equation is identical, so any values that satisfy the first equation will also satisfy the second equation.

There will be an infinite number of solutions. There will never be no solution.

__

<u>Example</u>:

  x + y = 4

  -x -y +4 = 0

Adding the two equations gives ...

  (x +y) +(-x -y +4) = (4) + (0)

  4 = 4

The solutions to this system are all values of x and y such that x+y=4. There are an infinite number of such solutions.

21. Jim loves nuts. He plans to spend at most $24 to buy cashews and peanuts for after work
FinnZ [79.3K]

He can buy 5 of the $3 nut and 1 of the $5 nuts.

5x3=15

5x1=5

15+5=20 and that’s less than 24.

So Jim can use $20 to buy the $3 one 5 times and the $5 one 1 time.

an assembly line worker at Rob's Bicycle factory adds a seat to a bicycle at the rate of 2 seats in 11 minutes. Write a proporti
LuckyWell [14K]
Rate = 2 seats/11 minutes = 2/11  seats/min

Therefore the time required for s seats is
(m \, min) =  \frac{s \, seats}{ \frac{2}{11} \,  \frac{seats}{min} } =  \frac{11s}{2} \, min
That is,
m = (11s)/2 min

When s = 16, obtain
m =  \frac{11(16)}{2} = 88 \, min

When s = 19, obtain
m =  \frac{11(19)}{2} = 104.5 \, min

Answers:
m = \frac{11s}{2}
When s = 16, m = 88 min
When s = 19,  m = 104.5 min
