The numbers represented by variables w and y on the number line are integers.
mixas84 [53]

<u>Option A)</u> when y=6 and w= 2, <u>Option B)</u> when y=4 and w=-1 are the TWO correct choices.

Step-by-step explanation:

The given inequality is w<x<y and x>2.

<u>step 1</u>: let us <u>assume that x=3</u>, since it is given that x>2.

<u>step 2</u>: substitute the value of x=3 and each options in the inequality

<u>step 3</u>: option A) w=2, y=6. Then w<x<y = 2<3<6 (the condition satisfies).

            option B) w= -1, y=4. Then w<x<y = -1<3<4 (the condition satisfies).

            option C) w= 0, y=2. then w<x<y ≠ 0<2<2 (does not satisfies).

            option D) w= -2, y=0. then w<x<y ≠ -2<2<0 (does not satisfies).

            option E) w= -4, y= -1. then w<x<y ≠ -4<2<-1 (does not satisfies).

What is the domain of the function f(x) = 2x+5?
Damm [24]
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.
