Answer:

1.) Arithmetic. common difference: 4

2.) Arithmetic. common difference: 4

3.) Not arithmetic.

Svet_ta [14]2 years ago

Answer:

Step-by-step explanation:

The first two have a common difference of 4

2 6 10

To get from 2 to 6 you need to add 4 to the 2.

-7 -3 1

Add 4 to -3 and you get 1. This works.

The last one seems to be playing hop scotch all over the place (hop scotch is not a technical term. It is just by way of saying it's not arithmetic).

Identify the ordered pair that represents the vector from a(1,6) to b(2,-3) and the magnitude of ab
aliina [53]

Answer: magnitude ab = 9.06

Step-by-step explanation:

The vector coordinates will be represented with ( X , Y )

Magnitude of ab will be

ab^2 = (X2 -X1)^2 + (Y2 -Y1)^2

ab^2 = (2 -1)^2 + (-3 -6)^2

ab^2 = 1^2 + 9^2

ab^2 = 1 + 81

ab = 9.06

Which of the lines graphed has a slope of -1/2 and a y-intercept of 3
MAXImum [283]

Answer:

The correct option is C).

Figure show the line with slope of -1/2 and a y-intercept of 3

Step-by-step explanation:

The equation of line is given by y=mx+c.

Where m is slope and c is y-intercept.

Given that line has slope

m=\frac{-1}{2} and c=3

Thus equation of line will be

y=mx+c.

y=\frac{-1}{2}x+3

To plot the line we need at least two points

Take x=0

y=\frac{-1}{2}x+3

y=\frac{-1}{2}0+3

y=3

The required point is A(0,4)

Take x=2

y=\frac{-1}{2}2+3

y=2

The required point is B(2,2)

Using this points to graph the given equation of line

Figure show the line with a slope of -1/2 and a y-intercept of 3

The correct option is C).

13.02-6y=8y using the method of solving linear equations
gregori [183]

well add -6y to 6y which equals 0 then add 8y to 6y which equals 14y

now you have 13.02=14y 

now you can divide 13.02 divided into 14 which equals 0.93

0.93 = y

Is this the relation R:={(2,1),(3,1),(5,5),(7,5)} a function?
fredd [130]
<h3>Answer: Yes, it is a function</h3>

This is a function because there are no x values that repeat.

If we had repeated x values, then this would mean a certain input x leads to multiple outputs y, and that would not make it a function.

For instance, if we had (2,1) and (2,2) at the same time, then the input x = 2 leads to multiple outputs y = 1 and y = 2 at the same time. A function would not be possible in this example.

A function is only possible if any input x leads to exactly one output y. It is possible for y to repeat itself and still have a function.
