What is the output for a graph y=x/3 + 5 when the input value is 6

Pavel [41]

It means y=6/3+5.
6/3 is 2.
so y=2+5
2+5=7
y=7 is your answer :)

What are the phase shift and period for the function y = 5cos[9(θ − 30°)] − 2?

svetoff [14.1K]

$\bf \qquad \qquad \qquad \qquad \textit{function transformations}

% function transformations for trigonometric functions
\begin{array}{rllll}
% left side templates
f(x)=&{{ A}}sin({{ B}}x+{{ C}})+{{ D}}
\\\\
f(x)=&{{ A}}cos({{ B}}x+{{ C}})+{{ D}}\\\\
f(x)=&{{ A}}tan({{ B}}x+{{ C}})+{{ D}}

\end{array}$

$\bf \begin{array}{llll}
% right side info
\bullet \textit{ stretches or shrinks}\\
\quad \textit{horizontally by amplitude } |{{ A}}|\\\\
\bullet \textit{ flips it upside-down if }{{ A}}\textit{ is negative}\\\\
\bullet \textit{ horizontal shift by }\frac{{{ C}}}{{{ B}}}\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is negative, to the right}\\\\
\qquad if\ \frac{{{ C}}}{{{ B}}}\textit{ is positive, to the left}\\\\
\end{array}$

$\bf \begin{array}{llll}

\qquad \frac{\pi }{{{ B}}}\ for\ tan(\theta),\ cot(\theta)
\end{array}$

so, with that template in mind, let's see

$\bf y=5cos[9(\theta-30^o)]-2\implies y=5cos\left[9(\theta-\frac{\pi }{6}) \right]-2
\\\\\\
y=5cos(9\theta-\frac{3\pi }{2})-2\\\\
-------------------------------\\\\
\begin{array}{lllcclllll}
y=&5cos(&9\theta&-\frac{3\pi }{2} )&-2\\
&\uparrow &\uparrow &\uparrow &\uparrow \\
&A&B&C&D
\end{array}\\\\
-------------------------------\\\\$

$\bf \textit{horizontal/phase shift}\implies \cfrac{C}{B}\implies \cfrac{-\frac{3\pi }{2}}{9}\implies \cfrac{-\frac{3\pi }{2}}{\frac{9}{1}}
\\\\\\
-\cfrac{3\pi }{2}\cdot \cfrac{1}{9}\implies -\cfrac{\pi }{6}\\\\
-------------------------------\\\\
period\implies \cfrac{2\pi }{B}\implies \cfrac{2\pi }{9}$

What is the answer and steps to this equation -3(3+x)+4(x-6)=-4

DENIUS [597]

Answer:

x = 29

Step-by-step explanation:

-3(3 + x) + 4(x - 6) = -4

Distribute -3 by the first set of parentheses and distribute 4 by the second set of parentheses.

-9 - 3x + 4x - 24 = -4

Collect like terms on the left side.

x - 33 = -4

Add 33 to both sides.

x = 29

Practice Question:

mafiozo [28]

The correct option of the function is C. (f+g)(x)= 6x^3 - 2x^2 + 4x - 8.

<h3>What is a function?</h3>

The function is a type of relation, or rule, that maps one input to specific single output.

Given;

f(x)= 3x^2 + 4x - 6

g(x)= 6x^3 - 5x^2 - 2

So,

(f + g)(x) = (3x^2 + 4x - 6) + (6x^3 - 5x^2 -2)

(f + g)(x) = 3x^2 + 4x - 6 + 6x^3 - 5x^2 - 2

Now, like terms and in order of exponent

(f + g)(x) = 6x^3 - 2x^2 + 4x - 8

Therefore, the correct option is C. (f+g)(x)= 6x^3 - 2x^2 + 4x - 8.
