Answer:

Range \rightarrow all real numbers less than or equal to 0 \rightarrow ( - ∞ , 0 ]

Step-by-step explanation:

For visual understanding a graph of the  function is attached with the answer.

  • For calculating the range of any modulus function you need to know that if modulus is there across any function then the output will be always positive.

For example: x has a range of ( - ∞ , + ∞ ) but |x| has a range of [ 0 , + ∞ ). Similarly range of |x + 1| is [ 0 , + ∞ ).

  • If you multiply the modulus function with a negative sign then the output will always be negative.

For example: Range of |x| is [ 0 , + ∞ ) but range of -|x| is ( - ∞ , 0 ]. Similarly range of -|x + 1| is ( - ∞ , 0 ]

  • Range in this case won't be affected on multiplying a positive constant with the modulus function.

Therefore the range of f(x) = -2|x + 1| will be ( - ∞ , 0 ].

(NOTE : <em>[a,b] means all the numbers between 'a' and 'b' including 'a' and 'b'.</em>

<em>(a,b) means all the numbers between 'a' and 'b' excluding 'a' and 'b'.</em>

<em>(a,b] means all the numbers between 'a' and 'b' including only 'b' not 'a'.</em>

<em>[a,b) means all the numbers between 'a' and 'b' including only 'a' not 'b'.</em>

<em>{a,b} means only 'a' and 'b'.</em>

<em>{a,b] or (a,b} doesn't mean anything.</em> )

Answer:

c(X)=R(X)

125x+18000=215x

18000=215x-125x

18000=90x (divede both sides by 90)

X=200

A 90 ° angle is divided into 2 angles. Find the size of the angles. 3x+15 and 2x+25
fenix001 [56]

The two angles are 45 degrees.

Step-by-step explanation:

You are just halfing the 90 degree angle, so all you have to do is divide 90 by two, and you have 45.
