<u>Answer: </u>

If f(x) = -(-2x - 5), then f(-5) is equal to -5

<u>Solution:</u>

Given that the function is f(x) = -(-2x – 5)

We are asked to find the value of f(-5)

<u><em>Finding value of f(-5):</em></u>

The value of f(-5) can be found by substituting -5 in place of “x” in the given function f(x) = -(-2x – 5)

f(x)= -(-2x-5)

For f(x) = f(-5),  

f(-5)= -(-2(-5)-5)

f(-5)= -(10-5)

f(-5)= -5

The value of the above given function f(x)= -(-2x-5) for x= -5 i.e., f(-5) is -5

If $6000 was expected in sales and only $5100 was attained, what reduced fraction represents sales attained?
ira [324]

The reduced fraction that represents the sales attained is 17/20

<h3>How to determine the fraction?</h3>

The given parameters are:

Expected = $6000

Attained = $5100

The fraction is represented as:

Fraction = Attained/Expected

So, we have:

Fraction = 5100/6000

Divide by 300

Fraction = 17/20

Hence, the reduced fraction is 17/20
