Answer:

1200

Step-by-step explanation:

Faceti o ecuatie pentru a o rezolva mai usor:

Intrebarea spune ca o treime a fost pentru un tricicleta si o a treia pentru o bicicleta, deci acestea sunt aceeasi valoare. Y este totalul.

    x + x + 400 = y

Exista trei parți ale ecuației și intrebarea spune ca doua treimi sunt utilizari pe bicicleta și tricicleta. Trebuie sa ramana o treime, deci pe a treia (x) trebuie sa fie aceeași cu 400.

Faceți o noua ecuație:

400 + 400 + 400 = ?

Adaugați numerele pentru a obține raspunsul: 1200

Write the set of real numbers in interval notation. {x | x ≥ −8}
Vikentia [17]
The answer is: [-8, \infty)

Which can be written as: [-8, infinity) 

This is the interval from -8 to infinity. So -8 is our left most point on the number line and infinity being our right most. There is no boundary on the right side.

Note how the left side has a square bracket and the right side has a curved parenthesis. This isn't a typo. The square bracket tells the reader "include the endpoint -8 as part of the solution set". The parenthesis tells the reader "do NOT include the endpoint infinity as part of the solution set". 

Rule: infinity and negative infinity is always paired with a parenthesis because these aren't numbers. It's impossible to reach infinity, therefore it's impossible to include it in the set of values. If you could include it, then that implies you ran out of numbers.
