206.5
Step-by-step explanation:
<em>It izz wat it izzzz!!!</em>
The answer would be 2 miles.
Answer choice A is incorrect as it is missing the variable 'x' in it.
Let's test answer choice B.
y = mx + b
m is the slope
b is the y-intercept
m = 2/3
b = -5
y = (2/3)x - 5
B is one of the answers.
Let's test answer choice C.
6y = 4x -30
y = (4/6)x - 30/6
y = (2/3)x - 5
Answer choice C is also correct.
Let's test answer choice D now.
y = (2/3)x - 5
Plug in (3,-3)
-3 = (2/3)(3) - 5
-3 = 2 - 5
-3 = -3
This is correct, so therefore D is also one of the answers.
Your answer is B, C and D.
Answer:
Domain: (-∞, -5) ∪ (-1, ∞)
Step-by-step explanation:
Note:
For f(x) > 0: See the points of x for which the graph of f(x) lies above the x-axis.
For f(x) < 0: See the points of x for which the graph of f(x) lies below the x-axis.
We need to find the domain of f(x) for which f(x) < 0
From the graph, we can tell:
f(x) < 0 on (-∞, -5) ∪ (-1, ∞)
Therefore: The domain on which the given graph f(x) is negative, is (-∞, -5) ∪ (-1, ∞)
