Answer:
Step-by-step explanation:
The given relations give rise to two equations:
b = g + 5
b + g = 21
Using the first to substitute for b in the second, we have ...
(g +5) +g = 21
2g = 16 . . . . . . . subtract 5
g = 8 . . . . . . . . . divide by 2
b = 8 +5 = 13
Ben got 13 presents; Gwen got 8.
The answer would be c for sure

Answer:
Domain is all real numbers.
Range is all real numbers.
Step-by-step explanation:
The domain is all the possible x values that are allowed.
The range is all the possible y values that are allowed.
Since this is a linear function, its graph is a straight line stretching from - infinity to infinity on both x and y axes, hence domain and range is all real numbers from - infinity to infinity.
This particular linear function (of form y = mx + c) has gradient m = 3 so slopes up to the right, and y-intercept c = - 5, an hence x-intercept 5/3.
The graph is sketched below and clearly extends indefinitely in terms of range and domain.

Answer: Which number line represents the solution set for the inequality 2x - 6 ≥ 6(x - 2) + 8? Summary: The inequality 2x - 6 ≥ 6(x - 2) + 8 which is represented by the number line above shows that the variable x takes on values that lie on the left-hand side of the number line value x = -1/2 and includes the point x = -1/2.
