Identify the domain of the graph given. *Don't forget the parenthesis or brackets*​
anzhelika [568]

Answer:

(-4,3)

Step-by-step explanation:

The domain of a function is all of its possible x-values.  In this graph, there is a y-value for every x-value between -4 and 3 except -4 and 3, because there are open dots at those points.  Therefore, the domain is (-4,3).  Use parenthesis because the function is not defined at x=-4 or x=3.

A weather forecaster says the temperature will be about-5C “give or take” 10 degrees. What is the greatest possible temperature?
IRINA_888 [86]

The greatest possible temperature is 5^{\circ} \mathrm{C} and least possible temperature is -15^{\circ} \mathrm{C}

<u>Solution:</u>

Given that according to weather forecaster the temperature will be about -5 degree celsius given or take 10 degree”

Need to determine greatest possible temperature and least possible temperature.

Give and take in given statement means a temperature can go up by 10 degrees and can go down by 10 degrees

So greatest possible temperature will be -5^{\circ} \mathrm{C}+10^{\circ} \mathrm{C}=5^{\circ} \mathrm{C}

Least possible temperature will be -5^{\circ} \mathrm{C}-10^{\circ} \mathrm{C}=-15^{\circ} \mathrm{C}

Hence according to weather forecaster, greatest possible temperature = 5^{\circ} \mathrm{C} and least possible temperature = -15^{\circ} \mathrm{C}

Three times x less than y is five times y plus two times x in a verbal sentence please help
tankabanditka [31]
SOLUTION:

As an equation it is:

y - 3x = 5y + 2x

If you are asking for it as a sentence ( I will do it as a written sentence as I unfortunately can't show you the sentence verbally as you had asked ), then it is as you had written in your question so:

Three times x less than y is five times y plus two times x

Or you could write is as:

y subtracted by three times x is equivalent to the sum of five times y and two times x.

Essentially, even with the small alterations that you can make to the phrasing and sentence structure, the concepts are the same so you can use one of the above answers or alter it as you please.

Hope this helps! :)
