Answer:
Domain : all real numbers
Range: All numbers greater than 2
Step-by-step explanation:
The shark. (Haha, I'm sorry.)
There are no restrictions on the x. X can be any real number.
The range, however, does have restrictions. The range has to be a number greater than 0.
Why?
Because any number that you put in for x won't make the range less than 2. If you put in zero for x, the range is 2.

Answer:
The player answer correctly 30 questions
Step-by-step explanation:
First we have to develop the information that gives us as 2 equations
x = correct answer
y = incorrect answer
z = score = 40
h = total answer = 50
2x - y = z x + y = h
2x - y = 40 x + y = 50
we clear the x of one equation and replace the value of x in the other equation
x = 50 - y
2x - y = 40
2(50 - y) - y = 40
100 - 2y - y = 40
-3y = 40 -100
y = -60/-3
y = 20
x = 50 - y
x = 50 - 20
x = 30
Answer:
Step-by-step explanation:
2(x + 2)/3 = 6
multiply by : 3
2(x + 2) = 18
2x+4 = 18
2x = 18-4=14
x=14/2
x=7
