Step-by-step explanation:

use point slope formula y-y₁=m(x-x₁)

find m which is slope  -1--1/-4--1= 0/-3= 0

Combine the following fractions. <br><br> a. 3/5 + 4/15 <br><br><br> b. 5/6 - 1/4
Ne4ueva [31]

Hello there! :)

Answer:

1. \boxed{\frac{13}{15} }

2. \boxed{\frac{7}{12} }

Step-by-step explanation:

1. 3/5+4/15

First, you multiply by numerator and denominator.

3*3=9

5*3=15

=\frac{9}{15}

Then, you had to combine by the fractions.

\frac{9}{15}+\frac{4}{15}

Add by the numbers from left to right.

9+4=13

<u><em>13/15 is the final answer.</em></u>

______________________________________________

2. 5/6-1/4

First, you multiply by 2 both sides of numerator and denominator.

5*2=10

6*2=12

10/12

3/12

\frac{10}{12}-\frac{3}{12}

Subtract by the numerator.

10-3=7

<em><u>7/12 is the final answer.</u></em>

Hope this helps!

Thanks!

Have a nice day! :)

Every orthogonal matrix is diagonalizable. O True O False
Simora [160]

Answer:

FALSE

Step-by-step explanation:

the correct answer is FALSE

A matrix is said to be orthogonal when it is  multiplied by its own transpose then the matrix comes out to be Identity.

                                      A^T.A = I

the basic condition for a matrix to be diagonalizable is that the matrix should be symmetric.

but an orthogonal matrix is not necessarily symmetric so, the statement is false.
