Answer:

53

Step-by-step explanation:

Let x = 1, 2, 3, 4, and add the values.

3 + (1^2 + 2 * 1) + (2^2 + 2 * 2) + (3^2 + 2 * 3) + (4^2 + 2 * 4) =

= 3 + 3 + 8 + 15 + 24

= 53

Look at the shape of the graph what can you predict about the mean and median beverage prices
alexdok [17]

If you read the question, you will see that the requirement is missing. By Googling the question, the complete content could be found here:

The mean price and median price are close together.

Answer: Option 2

<u>Explanation:</u>

The shape of the graph which is shown in the picture is symmetric. Since it is symmetrical in shape, most of the data is clustered together around the center. This center is the median. The mean will be close to the median, since most of the data values are close to this.

The graph shows that the prices of the beverages are some where near and close to each other. The prices are not at extreme ends and this makes the shape of the graph symmetrical. Had there been any kind of extreme ends, then the shape of the graph would not have been the same.

Use the graph to determine which statement describes f(x)
djverab [1.8K]

Answer:

f(x) does not have an inverse function, because its graph fails the horizontal line test. ⇒ A

Step-by-step explanation:

The vertical line test is used to show that the graph represents a

function or not

  • If the vertical line crosses the graph in more than one point, then the graph does not represent a function
  • If the vertical line crosses the graph in only one point in different positions, then the graph represents a function

The horizontal line test is used to show that the function has an

inverse or not

  • If the horizontal line crosses the graph of a function in more than one point, then the function has no inverse
  • If the horizontal line crosses the graph of a function in only one point in different positions, then the function has an inverse

Let us look at the given graph

→ The graph represents a parabola, which represents the function f(x)

∵ Any horizontal line drawn will cross the graph in more than one point

∴ f(x) has no inverse

∴ f(x) does not have an inverse function, because its graph fails the

  horizontal line test.

Which point-slope form equation represents a line that passes through (3,-2) with a slope of -4/5
son4ous [18]

Answer:

y + 2 = - \frac{4}{5}(x - 3)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - \frac{4}{5} and (a, b) = (3, - 2), hence

y - (- 2) = - \frac{4}{5}(x - 3), that is

y + 2 = - \frac{4}{5}(x - 3)
