For question 2 it is 15
Because: 4 time 6 is 24 and then you minus 9 which is 15
So there you have it the answer is 15
Answer: 1 and 4 are correct
Step-by-step explanation: good luck!
Answer:
amplitude = 3
Step-by-step explanation:
the amplitude is the vertical distance from center of the wave to the crest or the trough
Since it's a linear equation and there's a constant rate (given in the problem), we can choose our x - axis to be the time and the y - axis to be height. We choose it that way because you are going up in the elevator. The more time in the elevator, the higher you go.
Finding this equation uses the point slope formula, y - y₁ = m(x - x₁). It can be done with slope-intercept, y = mx + b too.).
First we need to get the slope of the line. Choose any two points, but be consistent and choose two y points as well as the matching x ones. Here, we use x₁ = 2, x₂ = 4, y₁ = 45, y₂ = 75. Slope, m, is y₂ - y₁ / x₂ - x₁.
m = 75 - 45 / 4 - 2
= 30 /2
= 15
Next, we use the slope of 15 and either of the points to find the linear equation. Choose the same (2, 45) x-y pair above, but any point will work.
y - 45 = 15 (x - 2)
y - 45 = 15x - 30
y = 15x + 15
So the linear equation representing this table us y = 15x + 15.
Answer:
(3, 4)
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs).
Such that a function can map each element of the domain into only one element of the range.
Then, if a "function" has:
f(x1) = y1
and
f(x1) = y2
It is mapping the input "x1" into two different outputs, then this is not a function.
Now, we know that the ordered pair (3, -4) is among the points on the graph of the function f(x)
(The first value is the input and the second one is the output)
Then the point that does not belong to the graph, is the point that has the same input and different output.
(3, 4)
Any of the other points could belong to the graph.
