Answer:

The correct option is C. The solution of given system of equations is (5,1).

Step-by-step explanation:

The given equations are

$x+y=6$ .... (1)

$x-y=4$ .... (2)

Add equation (1) and (2), to eliminate y.

$2x=10$

Divide both sides by 2.

$x=5$

The value of x is 5. Put this value in equation (1).

$5+y=6$

Subtract 5 from both the sides.

$y=6-5$

$y=1$

The value of y is 1. The point (5,1) is the solution of the given system of equations.

Therefore the correct option is C.

labwork [276]

Answer:

a) $G(x)= \sin x + 2$

b) The coordinates of P are

$\displaystyle \left( \frac{3\pi}{2},1\right)$

Step-by-step explanation:

Translation

The dashed line shows the graph of the function

$y = \sin x$

This function has a maximum value of 1, a minimum value of -1, and a center value of 0.

Graph G shows the same function but translated by 2 units up, thus the equation of G is:

$\boxed{G(x)= \sin x + 2}$

b) The coordinates of P correspond to the value of

$x = \frac{3\pi}{2}$

The value of G is

$\displaystyle G(\frac{3\pi}{2})= \sin \frac{3\pi}{2} + 2$

Since

$\sin \frac{3\pi}{2}=-1$

$\displaystyle G(\frac{3\pi}{2})= -1+ 2=1$

The coordinates of P are

$\displaystyle \left( \frac{3\pi}{2},1\right)$
