Find the equation, in point-slope form, of the line that passes -3 and passes through the point (1,2). plz show your work.
Maslowich
Substitute the given values for the parameters in the point-slope form of the equation of a line. That form is
  y - k = m(x - h)
for point (h, k) and slope m.

You have (h, k) = (1, 2) and m=-3, so your equation is
  y - 2 = -3(x - 1)

4. Let B = {(1,0,1),(0,1,2), (2, -1,0)}. (a) The vectors in B are dependent. Show this. (b) Find a non-trivial solution to an(1,
Vladimir79 [104]

Answer:

Step-by-step explanation:

Given are three vectors in set B.

To show that B is dependent

The determinant

\left[\begin{array}{ccc}1&0&1\\0&1&2\\2&-1&0\end{array}\right] \\=1(2)-1(2) =0

Hence vectors are dependent

b) The given equation a_1(1,0,1) + a_2(0,1,2) + a_3(2, -1,0) = 0.\\

Let us try parametrically

These 3 vectors are collinear and hence equation would be

\frac{x-1}{0-1} =\frac{y-0}{1} =\frac{z-1}{2-1} =s\\(x,y,z) = (1-s, s, 1+s)

c) Basis for B would be only 2 dimensional

i.e. any two vectors out of 3 form basis

The basis would be (1,0,1) and (0,1,2)

Answer:

0 and 2

Step-by-step explanation:

f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.

−1 −7/2 −9/2


0 −3 −3


1 −2 −3/2


2 0 0


3 4 3/2


4 12 3


5 28 9/2

There are two solutions to f(x) = g(x) which are x=0 and x=2.
