Answer:

f(1) = -4

Step-by-step explanation:

Given that,

f(x) = 2x-6

We need to find the value of f(1).

Put x = 1 in the above expression.

f(1) = 2(1)-6

= 2-6

= -4

So, the value of f(1) is equal to -4.

Answer:

x=$59.69

Step-by-step explanation:

We can create a proportion to find the answer.

Thus, we get 4 hr/$39.79=6 hr/$x.

Cross multiplying gives us 4x=238.74, and solving for x gives us $59.685.

We can round to $59.69.

Ron's recycle shop had an old paper-shredding machine. Business was good, so he bought a new paper-shredding machine. The old ma

Answer: 1 hour 20 minutes

Step-by-step explanation:

Given : The old machine could shred a truckload of paper in 4 hours.

Rate of work done by old machine = $\dfrac{1}{4}$

The new machine could shred the same truckload in 2 hours.

Rate of work done by new machine = $\dfrac{1}{2}$

Let 't' be the time taken by both of them working together , then we have the following equation:-

$\dfrac{1}{t}=\dfrac{1}{4}+\dfrac{1}{2}\\\\\Rightarrow\dfrac{1}{t}=\dfrac{1+2}{4}\\\\\Rightarrow\dfrac{1}{t}=\dfrac{3}{4}\\\\\Rightarrow t=\dfrac{4}{3}=1\dfrac{1}{3}\ \text{ hours}$

Since 1 hour = 60 minutes

Then, $\dfrac{1}{3}\ \text{ hours}=\dfrac{1}{3}\times60=20\text{ minutes}$

Hence, it will take 1 hour 20 minutes to shred the same truckload of paper if Ron runs both shredders at the same time.
