Answer:

x=9

Step-by-step explanation:

\frac{7x-3}{3x-2} =\frac{28+20}{20} \\\frac{7x-3}{3x-2} =\frac{48}{20} \\\frac{7x-3}{3x-2} =\frac{12}{5} \\36x-24=35x-15\\36x-35x=-15+24\\x=9

Determine o período e o conjunto imagem, construindo o gráfico de um período completo para cada função dada.a) por f(x) = 1+ 4 s
nataly862011 [7]

Answer:

The given functions are

f(x)=1+4sinx

f(x)=2sin(x-3)

The sine function has a standard period of 2 \pi by definition. However, this might change if we use a factor as coefficient of the x-varible, but in this case we don't have that.

Therefore, the period of both trigonometric functions is 2 \pi.

Now, the images of each function is the y-variable set values that defines each function.

So, the function f(x)=1+4sinx has an image defined by the set [-3,5]. It's impotant to notice that the range of a standard function is [-1,1], however, in this case, the function was shifted 1 unit up and it was streched by a factor of 4, that's why the standard image changes to [-3,5].

About the second function f(x)=2sin(x-3), the image set is [-2,2], because the function was streched by a factor of 2.

Additionally, the image attached shows the graph of the given functions.

Solve the simultaneous equation <br> 2x-5y=9<br> 3x+4y=2
Dmitriy789 [7]

Answer/Step-by-step explanation:

2x-5y=9

Add 5y  to both sides of the equation.

2x=9+5y

Divide each term by 2 and simplify.

Divide each term in 2x=9+5y by 2

\frac{2x}{2} =\frac{9}{2} +\frac{5y}{2}

Cancel the common factor of 2.

Divide x by 1.

x=\frac{9}{2} +\frac{5y}{2}

y=\frac{-9}{5} +\frac{2x}{5}

----------------------------------------------------------------------------------------------------------------

3x+4y=2

Add 4y to both sides of the equation

3x=2+4y

Divide each term by 3 and simplify.

Divide each term in 3x=2+4y by 3.

\frac{3x}{3} =\frac{2}{3} +\frac{4y}{3}

Cancel the common factor of 3.

Divide x by 1.

x=\frac{2}{3} +\frac{4y}{3}

y=\frac{-1}{2} +\frac{3x}{4}
