Does this graph represent a function? Why or why not?

artcher [175]

Answer:

Yes, this graph represents a function.

Functions can have a maximum of one y-value for every x-value. On a graph, this means it passes the vertical line test.

Step-by-step explanation:

The vertical line test is when a vertical line is passed though the graph. If at any point the vertical line touch more than one point on the graph, the graph is not a function. Vertical line test is also known as VLT.

Find the perimeter and area. (plz help with the answer)

ikadub [295]

Hello!

PERIMETER:

To find the perimeter of the trapezoid, simply add all sides together.

15 + 5 + 9 + 5 = 34

The perimeter is $\boxed{ \bf 34~units.}$

____________________________________________________________

AREA:

A = $\frac{1}{2}$ h( $b_{1}$ + $b_{2}$ )

A = $\frac{1}{2}$ 4(9 + 15)

A = $\frac{1}{2}$ 4(24)

A = 2(24)

A = 48

The area of the trapezoid is $\boxed{ \bf 48~units^2}$

Which points are 4 units apart?

xz_007 [3.2K]

The points that are 4 units apart are B and D

<h3>Complete question</h3>

Which points are 4 units apart? On a coordinate plane, point A is at (-2, 4), point B is at (3, -6), point C is at (-1, 0), point D is at (3, -2).

B and C

C and D

A and C

B and D

<h3>How to determine the points?</h3>

To do this, we simply calculate the distance using the following equation

$d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2$

Using the given points, we have:

$BC = \sqrt{(3+ 1)^2 + (-6 -0)^2} = 7.2$

$CD = \sqrt{(-1 - 3)^2 + (0 +2)^2} = 4.5$

$AC = \sqrt{(-2 + 1)^2 + (4 -0)^2} = 4.1$

$BD = \sqrt{(3 - 3)^2 + (-6 +2)^2} = 4$

Hence, the points that are 4 units apart are B and D

For an annual membership fee of $500,Mr.Bailey can join a country club that would allow him to play a round of golf for $35. Wit

IRISSAK [1]

Answer:

25 rounds

Step-by-step explanation:

Let

x -----> the number of rounds of golf

y ---> total charges to play

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

<em>Membership</em>

$y=35x+500$ ----> equation A

The slope is m=$35 per round

The y-intercept b=$500 (annual membership fee)

<em>Non-Membership</em>

$y=55x$ ----> equation B

The slope is m=$55 per round

The y-intercept b=$0

Equate equation A and equation B

$55x=35x+500$

solve for x

$55x-35x=500$

$20x=500$

$x=25\ rounds$

For x=25 rounds the cost to be the same with and without a membership
