Answer: D) No. The graph fails the vertical line test.
Explanation:
We are able to draw a single vertical line that passes through more than one point on the red curve. For example, we could draw a vertical line through x = 5 and have it cross the red curve at (5,4) and (5,-4).
So this is one example where the graph fails the vertical line test. It passes this test when such a thing doesn't happen. In other words, a function is only possible if any x input leads to exactly one and only one y output.
In this case, x = 5 leads to multiple outputs y = 4 and y = -4 at the same time. There are other x values which this occurs as well (any x values such that x > 1). So this is why we don't have a function.
So a day is 24 hours
24/6=4
4*5=20
so they spend 20 hours a day sleeping
here’s a full on equation
(24/6)*5
Answer:
Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.
Step-by-step explanation:
Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:
Groups: Not identified.
Exponents: Not identified, disparaging ₁.
Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21 <u>7x = 84</u>
Division: Derived, pertaining to multiplication, 7x = 84 ⇒ <em><u>x = 12</u></em>
Addition: Aggregate constants ⇒ 5/2x = 3/4x +21
Subtraction: Abate algebraic groups ⇒ 7/4x = 21
