Answer:

It should be the top left graph where there is point (1,1) and (-1, -1) y = 1/x

Step-by-step explanation:

from the original graph, I see:

f(x) = 2/x because f(2) = 1 = 2/2

f(1/4)= 2/(1/4) = 2

...

so then f(2x) compresses f(x) horizontally by a factor of 2

so f(2x) = 2/(2x) = 1/x

The Jammers basketball team had a

goldfiish [28.3K]

Answer:

5 Games

Step-by-step explanation:

Step 1: State what is known

We know for every 5 games the win they lose 1 game

They won 5 games

Step 2: Define your variables

Let x represent how many games the Basketball team lost

Step 3: Create equation

$\frac{5}{1}=\frac{25}{x}$

Step 4: Solve for 'x'

Cross multiply to solve for 'x'

$5x=25$

$x=\frac{25}{5}$

x = 5

Therefore the will have lost 5 games

The population of a certain geographic region is approximately 103 million and grows continuously at a relative growth rate of 1

aev [14]

The population increases by a factor 1.0167 every year so the require figure is:
103 * 1 . 0167^5 = 112 million

5 to 2 = __ to 4 and also 14 to 21 = __ to 15

nasty-shy [4]

1) Set up proportions for the ratios:

$\frac{5}{2} = \frac{x}{4}$

Cross multiply the fractions:

$2x = 20$

Divide both sides by 2 to get x by itself.

$x = 10$

5 to 2 is equal to 10 to 4.
------------
2) Set up proportions for the ratios:

$\frac{14}{21} = \frac{x}{15}$

Cross multiply the fractions:

$21x = 210$

Divide both sides by 21 to get x by itself:

$x = 10$

14 to 21 is equal to 10 to 15.
------------
OPTIONAL:
To make 2) easier to solve, simplify 14 to 21.

$\frac{14}{21} / \frac{7}{7} = \frac{2}{3}$

Then, continue with the problem as described above:

$\frac{2}{3} = \frac{x}{15}$

$3x = 30$

$x = 10$

Find the measure using rigid transformations. Somebody please help me on this Geometry question.

Alika [10]

Angle A would be 40 degrees I’m sure because it is a rotation not a dilation (which changes the measurements including the lengths and degree of angles)

Hope I helped :)
