What is the interval notation for the compound inequality? x≤−4 or x≥5 (−∞, −4) or (5, ∞)
(−∞, −4] or [5, ∞)
(−4,5)
[−4,5]

(-∞, -4] or [5, ∞)

Step-by-step explanation:

Because the solutions for x can also be equal to -4 and 5, brackets are used.

And because the solutions for x can be any number less than -4 or any number greater than 5, -∞ and ∞ are used respectively.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

x-3y=4
