If they worked for k hours, the amount of work done would be \mathbf{ \dfrac{k(x+y)}{xy}}hours.

<h3>How do we determine the job done using algebraic expressions?</h3>

Algebraic expression involves the use of variables and their arithmetic operations.

Given that:

  • Mr. Inwood does a job in x hours, while
  • Mr. Lui can do it in y hours

If we have a function denoted by k (hours) indicating the work they both can do together. Then we can conclude that they can both work for:

\mathbf{=\dfrac{k}{x}+\dfrac{k}{y}}

\mathbf{ \dfrac{k(x+y)}{xy}}

Answer:

17.67 mpg

Step-by-step explanation:

The fuel efficiency is given by :

\eta=1.437+0.541\times s

We need to find the fuel efficiency for a speed of 30 mph

Put the value of s equals 30 mph in the above equation.

\eta=1.437+0.541\times 30\\\\\eta=17.67\ mpg

So, the required fuel efficiency is equal to 17.67 mpg.

Answer:

So the 1st, 2nd, & 3rd graphs all show continuous data. (I'll attach an image to show which ones I'm talking about)

Explanation:

This is because with continuous data, all points need to connect and it needs to continue. The 4th graph (with just points) would be discrete.

I hope this helps!! :)

Sorry I took so long...
