The slope is 3. If an equation is in the form
Y-Y1=M(X-X1), then M is the slope. therefore, 3 is the slope

Which function family are these 3? thanks..​

Answer:

1) Function; Linear Function (y=x)

2) Function; Exponential Function (y=bˣ)

3) Not a function.

Step-by-step explanation:

So, let's go through each table of values. I'm also going to graph them (see attached graphs) because it will make things simpler and provide a visual.

First, also recall what the definition of a function is. A function is a function if and only if an x only has <em>one</em> distinct y-value. No x can have two or more y-values. For instance, (1,2) and (1,3) is <em>not</em> a function between the x repeats. So, let's go through the choices:

1)

We have the table as shown. Let's plot the points. See TABLE 1:

First, there are no repeating x-values, so we can be sure that this is indeed a function.

Looking at the graph, we can see that this resembles a linear graph. So, the parent function of this is a line.

The parent function of a line is:

y=x

So, table 1 is associated with a linear function.

2)

Let's again plot the points. See TABLE 2.

Again, there are no repeating x-values, so this is also a function.

Looking at the graph, this resembles an exponential function. The function increases slowly at first but starts increasing increasingly fast. The parent function is thus an exponential function.

So, table 2 is associated with an exponential function.

3)

First, notice how all the x-coordinates are repeating. And since they do <em>not</em> equal the same thing, this is not a function.

Table 3 is not a function and so has no corresponding family function.

6x + 13 = 37<br><br> please provide reasoning
sladkih [1.3K]

6x + 13 = 37

6x = 37 - 13

6x = 24

x = 24/6

x = 4

Answer: x = 4

An important postulate in geometry states: "Through Point P, there is only one line parallel to ". What is the equation of line
telo118 [61]
At first we will find the slope of the line that <span>passes through the points A and B
</span>
<span>A ( -10,8), B(2,3)
slope = (Δy)/(Δx) = (3-8)/(2-(-10)) = -5/12

the require line is parallel to the line </span><span><span>passes through the points A and B
</span>∴ the slope of the line </span><span>that passes through Point X = -5/12
and have a general form
   y = m x + c
where m is the slope and c is constant
the constant can be calculated by substituting with the point x (-5,10) in the equation of general form
∴ 10 = (-5/12)*-5 + c
   c = 10 - 25/12 = 95/12
∴ y = (-5/12)x +95/12  ⇒⇒⇒⇒ multiplying the equation by 12

∴ 12y = -5x +95

When do we use the addition and subtraction formulas for sine or cosine?
777dan777 [17]
When we need the cosine of the sum of two angles, we use the addition formula for cosine.

When we need the sine of the difference of two angles, we use the difference formula for sine.

Let's try one.  Say we needed to know

 \cos 15^\circ&#10;

We're only expected to know the trig functions of 30/60/90 and 45/45/90 triangles.  Fortunately, 15^\circ = 45^\circ - 30^\circ so

\cos 15^\circ = \cos( 45^\circ - 30^\circ )

= \cos( 45^\circ) \cos(30^\circ ) + \sin(45^\circ) \sin(30^\circ)

= \dfrac{\sqrt{2}}{2} \cdot \dfrac{ \sqrt{3}}{2} + \dfrac{\sqrt{2}}{2} \cdot \dfrac{1}{2}

\cos 15^\circ = \frac{1}{4} (\sqrt{6} + \sqrt{2})
