1. if a = -3.4 and b = -3.6, which of the following inequalities is not true?
a. a > b
b. |a| ≤ |b|
c. b ≤ a
d. |b| < a
2. which of the following numbers is not between -2.6 and 1.3 on the number line?
a. -1.8
b. 0.5
c. 1.4
d. -2.1
3. choose the symbol that makes a true statement.
-3.8 0.1
a. <
b. >
c. =

1. D

2. C

3. A

Step-by-step explanation:

1. -3.4 is in fact > -3.6

|-3.4| <= |-3.6| is correct since |-3.4|=3.4, and |-3.6| is 3.6

-3.6<=-3.4 true, is pretty much the same as the first option

|b|<a is false, since |b|=3.6 and 3.6 is not < -3.4

2. 1.4 is outside the tange (-2.6, 1.3)

3.  0,1 is greater than -3.8, hence, opt A. is the symbol that must be used

1. D. |b| < a

2. C. 1,4

3. A. <

Step-by-step explanation:

3. Obviously, a positive number is greater than a negative number.

2. The largest negative number is the least, so anything behind that is even more less. Obviously, 1,4 is ⅒ greater than 1,3 and is OUTSIDE the range, so this is a giveaway.

1. Absolute values are ALWAYS positive, so the absolute value of -3,6 is 3,6, and -3,4 remains the same. Positive numbers are greater than negative numbers, so this is a false statement. 3,6 is NEVER less than -3,4.

I am joyous to assist you anytime.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
