Answer:

1/4

Step-by-step explanation:

because when you take it from where the 10 and 40 meet to where the 50 adn 50 meet it is over 1 and up 4 which is your fraction. 1/4

Answer:

  4

Step-by-step explanation:

When trying to determine slope from a graph, it is useful to choose points on the graph where the line crosses grid intersections. For this graph, two such points are ...

  (x, y) = (40, 10)  and  (50, 50)

The "rise" between these two points is the difference of their y-coordinates: 50 -10 = 40.

The "run" between these two points is the difference of their x-coordinates: 50 -40 = 10

The slope of the line is the ratio of "rise" to "run":

  m = rise/run = 40/10 = 4

The slope of the line is 4.

__

<em>Additional comment</em>

This graph has scales that are 10 units between grid lines in both the x- and y-directions. This means you can also find the slope by counting grid squares. The points above differ by 4 grid squares in the vertical direction, and 1 grid square in the horizontal direction. Using grid square counts instead of coordinate value differences, we have ...

  m = rise/run = 4/1 = 4

which of the following represents a relation that is not a function? a. x -8 -6 7 10 y 33 31 39 33 b. x -8 -6 0 3 y 33 31 39 33
boyakko [2]
X => -8 -6 -8 3
y => 33 31 39 33
is not a function because the x value -8 results to two different y-values 33 and 39.

PLEASE HELP ME W THIS QUESTION

Answer:

J

Step-by-step explanation:

If the side of the shape is increased by 3/2 then the total distance around the shape will be 3/2 bigger.

Example: If the pentagon has side length 2 then it becomes 2*3/2 = 6/2 = 3.

The original perimeter was 2+2+2+2+2 = 10.

The new perimeter is 3+3+3+3+3 = 15.

Did you notice that \frac{15}{10}=\frac{3}{2}? J is correct.

Polygon ABCD is dilated, rotated, and translated to form polygon A′B′C′D′. The endpoints of AB are at (0, -7) and (8, 8), and th
Anton [14]

Rotation and translation are rigid transformations, they don't change figure sizes. Dilation change figure sizes increasing or decreasing them by scale factor.

First, find AB and A'B' by the formula:

AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}= \sqrt{(8-0)^2+(8-(-7))^2}=\sqrt{8^2+15^2}=\sqrt{64+225}=\sqrt{289}=17,\\ \\A'B'=\sqrt{(x_{B'}-x_{A'})^2+(y_{B'}-y_{A'})^2}= \sqrt{(2-6)^2+(1.5-(-6))^2}=\sqrt{4^2+7.5^2}=\sqrt{16+56.25}=\sqrt{72.25}=8.5.

As you can see AB=2A'B'. This means that the segment AB was decreased twice to form segment A'B'. Then the scale factor is 1/2.

Find the missing length of the triangle. a= ? b=4 c=12 1/3
Llana [10]

Answer:

a = 12.93

Step-by-step explanation:

Convert to decimal: 12 1/3 = 12.3

Pythagoras (a^2 = b^2 + c^2):

4^2 = 16

12.3^2 = 151.29

16+151.29 = 167.29

a = √167.29

a = 12.93 (rounded to two decimal places)
