"which of the numbers below can be classified as an integer" and the options are . 10÷2 , -0.3 ,√20 ,. 0.4
1 answer:
Answer:
The number 10/2 = 5 is an integer.
Step-by-step explanation:
An integer is a whole number which cannot be expressed in fractions. For example, 1, 2, 3...
Integer can be positive, negative of zero.
It is a whole number so it is an integer.
- 0.3
It is not an integer as it has a fractional part.
It also has a fractional part, so it is not an integer.
0.4
It also has a fractional part, so it is not an integer.

Answer:
D
Step-by-step explanation:
Given a square with vertices at points (2,1), (1,2), (2,3) and (3,2).
Consider option A.
1st transformation will map vertices of the square into points
2nd transformation = reflection over y = 1 has the rule (x,2-y). So,
These points are exactly the vertices of the initial square.
Consider option B.
1st transformation will map vertices of the square into points
2nd transformation = reflection over x = 3 has the rule (6-x,y). So,
These points are exactly the vertices of the initial square.
Consider option C.
1st transformation will map vertices of the square into points
2nd transformation = reflection over y = -x + 7 will map vertices into points
These points are exactly the vertices of the initial square.
Consider option D.
1st transformation will map vertices of the square into points
2nd transformation = reflection over y = -x + 2 will map vertices into points
These points are not the vertices of the initial square.
