Answer:

11x + 14y - 10z

Step-by-step explanation:

firstly deal with sum part and then subtract,making sure that you add and subtract values with the same unknowns

(7z + 3y - 10x) + (9x - 12y - z)

then

(10x + 5y - 4z) - (6z - 9y - x)10

which fits into the linear equation
y = -2x + 1

Function 2
The rate of change or the slope of the line
(3 - 0) /(0 - (-1) = 3

The rate of change of function 1 is -2
The rate of change of function 2 is 3

What would be the solution to this Pythagorean/Trigonometric equation? (csc² A - 1) sen² A = cos² A

Anna007 [38]

Answer:

$(csc^2 A -1) sin^2 A = cos^2 A$

We know that $csc x= \frac{1}{sin x}$ and using this identity we have:

$\frac{sin^2 A}{sin^2 A} - sin^2 A = cos^2 A$

$1 = cos^2 A + sin^2 A$

And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:

$A= [X | x \in R]$

Step-by-step explanation:

For this case we have the following equation given:

$(csc^2 A -1) sin^2 A = cos^2 A$

We know that $csc x= \frac{1}{sin x}$ and using this identity we have:

$\frac{sin^2 A}{sin^2 A} - sin^2 A = cos^2 A$

$1 = cos^2 A + sin^2 A$

And if we remember the equation above represent the fundamental identity in trigonometry and is satisfied for every real number and we can say that the solution for this case is:

$A= [X | x \in R]$
