Find the slope of the line Y=-3x - 4

1 answer:

6 0

Let y=0 to find the x-intercept(s).
0=−3x−4

Add 4 to both sides.
4=−3x

Divide both sides by -3
-4/3 =x (fraction)

Switch sides.
x=−4/3 (fraction)

Let x=0 to find the y-intercept(s).
y=−3×0−4

Simplify
y=−4

With bases V1, V2 , V3 andw1, w2 , W3, suppose T(v1) = w2 and T(v2) = T(v3) = w1 + w3 . T is a linear transformation. Find the m

Answer:

See picture and explanation below.

Step-by-step explanation:

With this information, the matrix A that you can find is the transformation matrix of T. The matrix A is useful because T(x)=Av for all v in the domain of T.

A is defined as $T=([T(v_1)] [T(v_2] [T(v_3)])\text{ where }[T(v_i)]$ denotes the vector of coordinates of $T(v_i)$ respect to the basis (we can apply this definition because forms a basis for the domain of T).

The vector of coordinates can be computed in the following way: if $T(v_i)=a_1w_1+a_2w_2+a_3w_3$ then $[T(v_i)]=(a_1,a_2,a_3)^t$ .

Note that we have all the required information: $T(v_1)=0w_1+1\cdot w_2+0w_3$ then $[T(v_1)]=(0,1,0)^t$

$T(v_2)=T(v_3)=1\cdot w_1+0w_2+0w_3$ hence $[T(v_2)]=[T(v_3)]=(1,0,0)^t$

The matrix A is on the picture attached, with the multiplication A(1,1,1).

Finally, to obtain the output required at the end, use the properties of a linear transformation and the outputs given:

$T(v_1+v_2+v_3)=T(v_1)+T(v_2)+T(v_3)=w_2+w_1+w_1=w_2+2w_1$

In this last case, we can either use the linearity of T or multiply by A.

<em>Comment on the question</em>

Vectors can be represented a number of different ways. Components can be given in rectangular or polar form, and the presentation can be made as a row vector, column vector, sum of orthogonal unit vectors, and other ways. We assume this is supposed to be a column vector of the form ...

What information is shown on the horizontal axis of a bar chart?

Bad White [126]

The information shown on the horizontal axis of a bar chart is the qualitative class labels.

<h3>What is a bar chart?</h3>

A bar chart is a graph that is used to represent data graphically using rectangular bars. A bar charts has two axis:

The vertical axis or the y axis which shows the frequency of the observations.
The horizontal axis or the x axis shows the qualitative class labels.
