Sveta_85 [38]

We want to see if the given function represents a linear function.

We will see that yes, it does.

So we have the function:

y = f(x) = 30 + 5*x

And a general linear function is written as:

y = a*x + b

where a is the slope and b is the y-intercept.

Comparing these two, we can see that both have the same general shape, thus, our function is also a linear function.

A graph of our function also can be seen below, where it is evident that it is a line.

10 % off the regular price. what is the discount amount any price?
zloy xaker [14]

Answer:

Not really 100% sure how to answer this, but if you would like to find the price of any item 10% off, you would just multiply the price by 0.9

EX: item cost $100

$100 x 0.9 = $90

Meaning the price of the item after the discount is applied would be $90
