Answer:
the answer is -3
Step-by-step explanation:
-2(4x+4) becomes -8x+-8 then becomes -8x+-8+-4 you get -8x+-12 you add 12 to -12 it then gives you -8x=24 that makes it -x=3 you devide that by -1 and x=-3
REASONING The data sets show the years of the coins in two collections.
Your collection: 1950, 1952, 1908, 1902, 1955, 1954, 1901, 1910
Your friend’s collection: 1929, 1935, 1928, 1930, 1925, 1932, 1933, 1920
Compare the measures of center and the measures of variation for each data set.
Your collection's mean is
. Your collection's median is
. Your collection's range is
. Your collection's interquartile range is
. Your collection's mean absolute deviation is
.
Your friend's collection's mean is
. Your friend's collection's median is
. Your friend's collection's range is
. Your friend's collection's interquartile range is
. Your friend's collection's mean absolute deviation is
.

The graph is a straight line that passes through the origin.
For instance, the linear equation y = 6x is a direct proportion.
If the line doesn't pass through the origin, then it's not a direct proportion. The equation y = 2x+5 for instance is not a direct proportion.
Answer;
The exact length is 2√5 units. You can also use a calculator to get an approximate value, which is about 4.47 units
