Answer:

Ordered pair (x,y) is (6,2)

Step-by-step explanation:

Use the substitution method to solve the system of equations.

2x + 2y = 16    -----> first equation

y=x-4 -------> second equation

Divide the first equation by 2

2x + 2y = 16    -----> first equation

x+y=8    

Now solve for y, subtract x from both sides

y=-x+4    

Now plug in -x+8 for y in second equation

y=x-4 -------> second equation

-x+8=x-4  

Subtract x from both sides

-2x+8=-4  

Subtract 8 on both sides

-2x=-12  

Divide both sides by -2

x=6

now we plug in 6 for x in second equation

y=x-4 -------> second equation

y=6-4

y=2

Ordered pair (x,y) is (6,2)

If the terminal side of angle 0 in standard position intersects the unit circle at p (3/5,4/5). Find cos0 and sin0
Rina8888 [55]

Answer:

\sin \theta = \frac{4}{5}, \cos \theta = \frac{3}{5}

Step-by-step explanation:

Let be P(x,y) = \left(\frac{3}{5}, \frac{4}{5}  \right) the end of the terminal side of angle \theta in standard position, that is, an angle measured with respect to +x semiaxis. By Trigonometry, we know that the sine and the cosine of the angle are, respectively:

\sin \theta = \frac{y}{\sqrt{x^{2} + y^{2}}} (1)

\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}} (2)

If we know that x = \frac{3}{5} and y = \frac{4}{5}, then the sine and the cosine of the angle are:

\sin \theta = \frac{\frac{4}{5} }{\sqrt{\left(\frac{3}{5} \right)^{2}+\left(\frac{4}{5} \right)^{2}}}

\sin \theta = \frac{4}{5}

\cos \theta = \frac{\frac{3}{5} }{\sqrt{\left(\frac{3}{5} \right)^{2}+\left(\frac{4}{5} \right)^{2}}}

\cos \theta = \frac{3}{5}

Pls help me prove this
Levart [38]

Parallel lines

Lines that are always at a given distance from each other and never cross, is called the "parallel" line.

If a diagonal line (PS) interrupts two parallel lines and gives them equal angles, can say that these two lines are parallel. Because the angles are opposite to the vertex and has it opposite angles with other angle

Sorry i can not say this, Because the educational system is different
