Does this table represent a function? why or why not? x: 2 3 3 4 5 y: 1 4 3 2 5
gayaneshka [121]
Let's put the chart into ordered pairs:
(x, y)
(2,1)
(3,4)
(3,3)
(4,2)
(5,5)

In bold, we see that there are two y-values at x=3. This means that this relation fails the vertical line test (two points on the same verticle line). This is not a function. 

The answer options may be mis-written. 
The answer is no, because one x value corresponds to more than one y-value.

The greater of two numbers is six more
pickupchik [31]

Answer:

 

Let's begin by writing the mathematical equations given by the sentences.

 

Let X = smaller number

Let Y = larger number

 

The first sentence tells us

X + Y = 38

 

The second sentence tells us

X = Y/3 + 6

 

Since you weren't given a specific method to use, you can use either the substitution method or the elimination(addition) method, whichever works best for you.

 

Since the 2nd equation has the X isolated, I'm going to isolate the X in the first equation,

X = 38 - Y

 

Since both equations are equal to X, I can set them equal to one another and solve for Y.

Y/3 + 6 = 38 - Y

 

Y + 18 = 114 - 3Y

4Y = 96

Y = 24

 

Then use either of the two original equations to solve for X

X + Y = 38

X + 24 = 38

X = 14

Find the arc length of the
Agata [3.3K]

Answer:

Circle circumference = radius * 2 * PI

Arc Length = radius * 2 * PI * Central Angle / 360 degrees

Arc Length = 7 * 2 * PI * (1/4)

= 3.5 * PI

= 10.9955742876

Arc Length = 10.996 (rounded)
