Answer:

between 2009 and 2012

Step-by-step explanation:

(2009-2012): 604-258= 346

(2008-2011): 457-435= 22

Answer:

(4,-3) or -3

Step-by-step explanation:

2 - -8 =

2 + 8 =

10 / 2 =

5

-8 + 5 = -3

2 - 5 = -3

So, (4,-3)

Hope that helps!

Answer:

8/10

Step-by-step explanation:

Answer:

48

Step-by-step explanation:

B and C trisrct AD so

that means that

AB=BC=CD

M is the midpoint so AM =MD

M is also the midpoint of BC also so if MC equal 8 l, BM equal 8. We add 8 and 8 together to find the value of BC which equal 16. Since BC equal 16 and it trisects AD, AB equal 16 and CD equal 16. Add all together and we get 16+16+16=16×3=48

Answer:

5) 3/19

6)9/19

Step-by-step explanation:

there are 19 marbles altogether

Answer:

It should be 9/19

Step-by-step explanation:

since you have the option to draw a red or blue you add those numbers together. So it's asking what is the probability of drawing either marble.

Answer:The answer in a fraction is 405/916 and the decimal form is 0.44213973

…

Step-by-step explanation:

Answer:

34x-5 = 2x/27+10

or, 34x-5=(2x+270)/27

or, 918x - 135=2x+270

or, 918x-2x=270+135

or, 916x= 405

or, x = 0.44

Answer:

part b (2,-1)

Part c the lines intersect at (-20,-45)

Step-by-step explanation:

Answer:

The equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Step-by-step explanation:

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

In our case, we are given

The slope m = -1/2

Point (2, -3)

now substituting m = -1/2 and (2, -3) in the slope-intercept form of the line equation to determine the y-intercept

[tex]y = mx+b[/tex]

-3 = -1/2(2) + b

-3 = -1 + b

b = -3 + 1

b = -2

now substituting m = -1/2 and b = -2 in the slope-intercept form of the line equation

y = mx + b

y = -1/2x + (-2)

y = -1/2x - 2

Therefore, the equation which best describes the graph of a line that has a slope of - 1/2 and passes through the point (2,-3) will be:

Answer:

-6

Step-by-step explanation:

You divide -18 from 3, which is going to be -6.

Answer:

0.75

Step-by-step explanation:

Equation of the line: 0x+8

Slope: 0.75

Answer:

- [tex]\frac{1}{14}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] × - [tex]\frac{1}{7}[/tex] ( multiply numerators and denominators together )

= - [tex]\frac{1(1)}{2(7)}[/tex]

= - [tex]\frac{1}{14}[/tex]

Answer:

C) B>A

Step-by-step explanation:

if it doesn't make sense think of it like the number in between A and B is .5. You can visibly see that A is less than or below .5 and B is above or greater than .5, so B is greater than A.

Answer:

1: x = 10

2: x = 2

3: x = 5

Brainliest?!?!

Answer:

it is most likely D

Step-by-step explanation:

it is prolly d cuz all the other numbers are larger then the one side thats lebeled and uh the bc side is shorter.

Answer:

Please check the explanation.

Step-by-step explanation:

The slope-intercept form of the linear function  

[tex]y = mx+b[/tex]

where

The graph of y = mx + b is a straight line. Thus, y = mx + b represents a linear function.

Analzing the function y = –x + 5

Given the linear function

y = –x + 5

comparing with the slope-intercept form of linear equation

The slope m = -1

The y-intercept b = 5

Also, the graph of a linear function is a straight line.

Thus,

The function  y = –x + 5 represents  a linear function.

Analzing the Table Function

x        0     1     2     3

y        0     1     8     27

In order to identify whether the given table represents the linear function or not, we need to make sure the given function has a constant change x and y.

If there is a constant change in x and y, then it would be a linear Function otherwise it would not represent a linear function.

There is a constant change in x values.

i.e.

1 - 0 = 1

2 - 1 = 1

3 - 2 = 1

But, there is NOT a constant change in y.

i.e.

1 - 0 = 0

8 - 1 = 7

27 - 8 = 19

It is clear that the table does not have a constant change in y-values.

Therefore, the table function does not represent the linear function
