Answer 1

Where's the mathematical symbol that tells what kind of mathematical sentence it is?

Answer 2

sorry this is the wrong question this is the right one

Answer 3

sorry this is the wrong question this is the right one

Answer 4

sorry this is the wrong question this is the right one

Answer 5

sorry this is the wrong question this is the right one

Answer 6

I don't know if it is an equality or an inequality.

Answer 7

it is absolute value, take the [] off and you have 2x-9+47

Answer 8

Part 1: Change 3x + 2y = 10 to slope-intercept form. You must show all work. (2 points)

Part 2: State the slope and y-intercept (2 points)

Answer 9

2x+38

Answer 10

because you add the -9 and the 47 and bring down the 2x

Answer 11

and it was < or equal to 7

Answer 12

^and that confirms that it was a mathematical sentence not an expression.

Answer 13

Answer 21

And I'm guessing you probably didn't check your work either.

Answer 22

Ok I appreciate all the medals i can get so if you think i did a great job i would appreciate it

Answer 23

|2x-9|+4 ≤ 7
|2x-9| ≤ 7 - 4
|2x-9| ≤ 3

-3 ≤ 2x-9 ≤ 3

-3+9 ≤ 2x ≤ 3 + 9
6 ≤ 2x ≤ 12
6/2 ≤ x ≤ 12/2
3 ≤ x ≤ 6

Answer 24

The important thing to remember here is that

|x-a|≤ b can be re-written as -b ≤x-a ≤b

Answer 25

In English it means that the absolute value of a number less than or equal to b:
|x-a|≤b

means that same as a number between negative and positive b:
-b ≤ x -a ≤ b
