Answer:

x = 1/3 and y = 3

Step-by-step explanation:

It is given the system of equations

3x + 2y = 7   ----(1)

-3x + 3y = 8    ----(2)

<u>To find the solution</u>

Add eq(1) and eq (2) we get,

3x + 2y = 7   ----(1)

<u>-3x + 3y = 8</u>    ----(2)

 0 + 5y = 15

y = 15/5 = 3

Substitute the value of y in eq(1)

3x + 2y = 7   ----(1)

3x + 2*3 = 7

3x + 6 = 7

3x = 7 - 6 = 1

x = 1/3

Therefore

x = 1/3 and y = 3

(1Q) Find a function for the graph below
anzhelika [568]

ANSWER

C.

f(t) =  - 3 \sin(3t)

EXPLANATION

The given function has range:

-3≤f(t)≤3

This implies that, the amplitude is

|a|  = 3

The function is symmetric with respect to the origin so this is a sine function.

This function is again reflected in the x-axis, hence

a=-3.

The period of this function is

\frac{2\pi}{b}  = \frac{2\pi}{3}

This implies that, b=3,

hence the equation of the function is

f(t) =  - 3 \sin(3t)
