Identify the solution set of the equality using the given replacement set

option C

Step-by-step explanation:

x<-4

to find solution set using the given replacement set we use above inequality x<-4

We pick all the numbers from solution set that are less than -4

-10 is less than -4

-4.3 is less than -4

-3.9 is greater than -4

-4 is equal to -4

2 is greater than -4

6.5 is greater than -4

So two numbers that are less than -4 are -10  and -4.3

Option C is correct.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
