Question

При каких х значения функции у=4,5-0,5х не больше 4,5?

Answer 1

Вот, как то так! Надеюсь, что помогла)

Answer 2

y <= 4.5

4.5 - 0.5x <= 4.5

-0.5x <= 1

x>=2

х ∈ [2;+∞)

Answer 3

To find the values of x for which the function y = 4.5 - 0.5x is not greater than 4.5, we need to solve the inequality:

y = 4.5 - 0.5x ≤ 4.5

First, subtract 4.5 from both sides of the inequality:

0.5x ≥ 0

Now, divide both sides by 0.5:

x ≥ 0

So, the values of x for which the function y = 4.5 - 0.5x is not greater than 4.5 are all values of x greater than or equal to 0. In other words, the function is not greater than 4.5 for any positive value of x or when x is equal to 0.
