Answer:
I'm not really sure what the question might be asking or if I've been given all the information but this is how you would solve it as (-2,4] meaning any real number between these will give you a real x on the domain.
Step-by-step explanation:

X-2=10
or
10=x-2
this is because it says "2 less than a number is 10" so we can infer that 2 is less than a number (x) so knowing that less than means subtract x-2=10 or you can put it as 10=x-2
Answer:
Females = 17 and males = 23
Step-by-step explanation:
Given that,
Total no of students in the class = 40
Let no. of females = x
No. of males = 6+x
ATQ,
Total students = males + females
40 = x+6+x
40-6 = 2x
34 = 2x
x = 17
Hence, there are 17 females and (6+17= 23) males.
