Answer:
y-x-1 < 0
Step-by-step explanation:
according to the graph (0,1) and (-1,0) lies on the doted line,
equation of the dotted line is y-x-1=0
shaded region = y-x-1 < 0
For multiplying fractions you basically just multiply across so for the green one it would be 1x4=4 so you would have 4 as the numerator for the answer and the bottom is 2x8=16 so that would be the denominator your answer would be 4/16 for the green question
Answer:

Step-by-step explanation:
( 1 ) 11/3
can be converted to mixed fractions to 
Therefore, 11/3 is at least around 3, almost 4. It could be more than 3.5 by approximation but not exactly 4.
( 2 ) √20

We know that
so
which means approximately,
can be either at least 4.3 up to 4.4
( 3 ) √17
We know that
so
can be at least 4.1 up to 4.2, but it’s obvious that the square root of 17 is less than square root of 20 since
for a > b
Hence, from least to greatest:

10 - 4 = x
10 - 4 = 6
x equals 6
