$cscx=\frac{1}{sinx};\ sin^2x+cos^2x=1\to cos^2x=1-sin^2x\\----------------------------\\\\csc^2xcos^2x=csc^2x-1\\\\L=csc^2xcos^2x=\frac{1}{sin^2x}\cdot cos^2x=\frac{cos^2x}{sin^2x}\\\\R=csc^2x-1=\frac{1}{sin^2x}-1=\frac{1}{sin^2x}-\frac{sin^2}{sin^2x}=\frac{1-sin^2x}{sin^2x}=\frac{cos^2x}{sin^2x}\\\\\boxed{L=R}$

Which statements are true about the ordered pair(-1, -4) and the system of equations?

Lesechka [4]

Answer:

a) when (-1,-4) is substituted into the first equation

then the equation is satisfied

b) The ordered pair(-1, –4) is a solution to the system of linear equations.

Step-by-step explanation:

Step(i):-

Given that the system of equations

x -y =3 ...(i)

7x -y =-3 ...(ii)

subtracting (i) and (ii) equations , we get

x -y -(7x-y) = 3 -(-3)

x - y - 7x + y = 6

- 6x = 6

x = -1

Step(ii):-

Substitute x=-1 in equation (i), we get

x -y =3

-1 -y = 3

y = -1-3

y = -4

The solution of the given system of equations (-1,-4)

Final answer:-

a) when (-1,-4) is substituted into the first equation

then the equation is satisfied

b) The ordered pair(-1, –4) is a solution to the system of linear equations.
