Simplify the following expression by combining like terms.
9 - 12x + 2x - 5

4-10x

Step-by-step explanation:

like terms: 9 and -5, -12x and 2x

9-5= 4

-12x+2x= -10x

Put them together:

4-10x

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

the answer for the second equation is (4,0)
