Perpendicular to y = 3x + 4 through (0, -2)

1 answer:

7 0

If a line is perpendicular, is has a negative reciprocal slope
The slope for the new line will be -1/3x
To find b, plug in what you know
-2=-1/3(0)=b
-2=b
Now you have everything that you need
your line is y= -1/3x - 2
Hope this helps!

Help me please i do not understand.

Answer:

x = 1

Step-by-step explanation:

given h(x) = 3x + 1 and h(x) = 4 , then equating

3x + 1 = 4 ( subtract 1 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

Find the eigenvectors and eigenvalues for the matrix. A =<br> [2 1 <br> -1 2]

denis23 [38]

Answer:

Step-by-step explanation:

Given matrix A is 2x2

A-kI =0 gives

$\left[\begin{array}{ccc}2-k&1\\-1&2-k\end{array}\right] =0\\\\(2-k)^2+1=0\\2-k=i,-i\\k =2-i, 2+i$

Eigen values are 2-i, 2+i

a) k =2-i

$\left[\begin{array}{ccc}i&1\\-1&i\end{array}\right] =0\\$

i.e. x1=ix2

OR Eigen vector is (i,1)

b) k =2+i

$\left[\begin{array}{ccc}-i&1\\-1&-i\end{array}\right] =0\\$

i.e. x1=-ix2

OR Eigen vector is (-i,1)
