Mathematics

To simplify, you just need to multiply 9 by both 3t and 4b separately:
9(3t + 4b) = (9)(3t) + (9)(4b) = 27t + 36b
That what to simplify means. Hope this helps!

Write an equation that has a graph with the shape of y = x^2, but shifted left 3 units.
svetoff [14.1K]
\bf \qquad \qquad \qquad \qquad \textit{function transformations}

% left side templates
\begin{array}{llll}
f(x)=&{{  A}}({{  B}}x+{{  C}})+{{  D}}
\\ \quad \\
y=&{{  A}}({{  B}}x+{{  C}})+{{  D}}
\\ \quad \\
f(x)=&{{  A}}\sqrt{{{  B}}x+{{  C}}}+{{  D}}

f(x)=&{{  A}} sin\left({{ B }}x+{{  C}}  \right)+{{  D}}
\end{array}\\\\

\bf % template detailing

\\\\
\bullet \textit{ horizontal shift by }\frac{{{  C}}}{{{  B}}}\\
\left. \qquad  \right. if\ \frac{{{  C}}}{{{  B}}}\textit{ is negative, to the right}\\\\
\left. \qquad  \right.  if\ \frac{{{  C}}}{{{  B}}}\textit{ is positive, to the left}\\\\

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

\bf y=x^2\implies 
\begin{array}{llll}
y=(&1x&-0)^2\\
&B&C
\end{array}

so, just change C to +3, thus C/B is 3/1

Reduce the fraction:<br> 7b-14b²/42b²21b
ch4aika [34]

Answer:

(1-2b)/126b^2

Step-by-step explanation:

(7b-14b^2)/(42b^2*21b)

factor out the 7b,

[7b(1-2b)]/882b^3

[7b(1-2b)]/[7b(126b^2)]

cancel out the 7b's

(1-2b)/126b^2
