In a sale, there is 50% off all prices. A chair costs ?17.50 in the sale. How much was it before the sale?

In order to solve this problem, you double the sales price!

$17.50 x 2 = $35.00

The original price would be $35.

Hope this helps!

Naomi is a songwriter who collects royalties on her songs whenever they are played in
barxatty [35]

Equations can be solved in several ways; one of these ways is the graphical method.

The number of commercials, x, and  the number of movies, y, on which Naomi's songs were played are 5 and 2, respectively.

Let:

<em />x \to<em>  commercials</em>

<em />y \to<em> movies</em>

<em />

She earned a total of $300.

This is represented as:

20x + 100y =300

Her songs were played on 3 more commercials than movies.

This is represented as:

x = 3 + y

See attachment for the graphs of

20x + 100y =300

x = 3 + y

From the graph, the lines of both equations intersect at:

x = 5

y = 2

This means that:

  • <em>The number of movies is 2</em>
  • <em>The number of commercials is 5</em>

Does this set of ordered pairs represent a function? Why or why not? {(–1, 5), (0, –3), (2, 7), (4, 0), (7, 5)} A. No, because t
iVinArrow [24]

9514 1404 393

Answer:

  C. Yes, because every x-value corresponds to exactly one y-value.

Step-by-step explanation:

The list of x-values is {-1, 0, 2, 4, 7}. We note that no two are the same, so this is a functional relation.

The set of ordered pairs is a function because each x-value corresponds to exactly one y-value.
