What inequality expression is this

Mathematics
1 answer:
lozanna [386]3 years ago
7 0

Answer:

≥

Step-by-step explanation:

First, let me clarify what the inequality expressions are and what they signify.

≥ means greater than or equal too

≤ means less than or equal too

< means less than

> means greater than

The text says students in middle school must be 10 years <em>or older. </em>That gives me a clue that students in middle must be either 10 years old, or older than ten years old. Greater than 10, or equal to ten. The inequality symbol that compliments that is the greater than or equal to symbol, ≥. So, the inequality symbol that goes with the text is the greater than or equal to sign, ≥.

Determine whether the formula describes y as a function of x. Explain your reasoning.. . y = -x
Alex17521 [72]
The given formula above, y = -x, is a sample of a function. A function is an equation that would give only one value of y for every value of x. This is the same as saying that exactly one output is set by each input. If we take x = -1, the value of y is 1 and nothing else.

Andrea Is selling candles as a fundraiser she spent $50 on supplies for making the candles she plans to sell candles for $10 eac
dalvyx [7]

COMPLETE QUESTION:

Andrea is selling candles as a fundraiser. She spent $50 on supplies for making the candles. She plans to sell the candles for $10 each. Her profit can be modeled by C(x) = 10x - 50.

What type of function is this?

What is the domain and range of the function?

Answer:

- This function is one-to-one

- Domain D = {x: x is a whole number ≤ Z}

- Range R = {y: y is in -50, ..., (10Z - 50)}

Where Z is the number of candles she could produce with $50.

Step-by-step explanation:

Given that her profit is modeled by C(x) = 10x - 50

- This function is one-to-one, because it is in the form f(x) = y.

Let the number of candles she could make with $50 be Z.

Then the domain is the set of all whole numbers less or equal to Z.

D = {x: x is a whole number ≤ Z}

If there are infinite number of candles she could make with that money, then

D = (-infinity, infinity)

When x = 0, we have C = -50

When x = Z, we have C = 10Z - 50

The range is then given as

R = whole numbers from -50 up to (10Z - 50)

R = {y: y is in (50 -Z), ..., (10Z - 50)}

If there are infinite number of candles she could make with that money, then

R = (-infinity, infinity)
