Which equation is a linear function? y=2^x -1 y=x/2-5 y=2/x +3 y=x^2 +7

Umnica [9.8K]

Answer:

Second Choice.

Step-by-step explanation:

$y = mx + b$

That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.

So we can cut out the first and last choice.

Then we have only two choices which are

$y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3$

The second equation is called Rational Function where a variable is a denominator.

Therefore, the correct answer is second choice.

Tim has read 10% of a book. He has 45 more pages to finish. How many pages are there in the book?

Monica [59]

if Tim has read 10% of the book, that means he still hasn't read 90% of it yet, and we know that that 90% is 45 pages, so say the book has a total amount of pages of "x", which is 100%.

$\begin{array}{ccll} pages&\%\\ \cline{1-2} 45&90\\ x&100 \end{array}\implies \cfrac{45}{x}=\cfrac{90}{100}\implies \cfrac{45}{x}=\cfrac{9}{10} \\\\\\ 450=9x\implies \cfrac{450}{9}=x\implies 50=x$

Can I get some help with this plz?

valina [46]

Answer:

I think on the y-axis you should count by 4s so its more spaced out and label the x axis (which is the line going horizontaly) 1-6 spaced out and you got numbers 1-3 correct I think your name is good you could also put number of bacteria vs number of days :)

Hope this helps
