Which inequality represents all values of x for which the product below is defined

zavuch27 [327]

Answer:

(-∞, -2) ∪ (0, ∞)

Step-by-step explanation:

Multiply together the (7x) and the (x+2), obtaining 7x^2 + 14x. This is the correct argument (input) to Answer A.

Since the domain of the square root function includes "all real numbers equal to or greater than 0," we set 7x^2 + 14x = to 0. This factors to the original 7x*(x+2), set equal to 0. The roots are 0 and -2.

These two values create three intervals: (-∞, -2), (-2, 0) and (0, ∞).

Choosing test numbers, one from each interval: {-5, -1, 1}.

7x^2 + 14x is + at x = -5, - at x = -1, and + at x = 1.

Thus, the domain of this function is (-∞, -2) ∪ (0, ∞). In other words, the product shown is defined on (-∞, -2) ∪ (0, ∞).

HELLLLLLLLPPPP The value of x is

NeTakaya

Angle QRT is an exterior angle to the triangle. The rule is that the exterior angle of a triangle is equal to the sum of its remote interior angles. Those remote interior angles are angle RTS and angle TSR. So our equation is $9x=(5x)+(9+x)$ . We can remove the parenthesis and simplify by combining like terms to get 9x = 5x + 9 + x and 9x = 6x + 9 and 3x = 9. That means that x = 3.

Order pair of x=y+2 and 2y=x-1

EastWind [94]

x=y+2
2y=x-1
substitute x=y+2 into 2y=x-1

2y=x-1
2y=y+2 -1
2y - y = 1
y = 1

x=y+2
x=1+2
x=3

answer
x = 3 and y = 1
