How can you use scale factor to determine the scale drawing?

To find the scale factor, locate two corresponding sides, one on each figure. Write the ratio of one length to the other to find the scale factor from one figure to the other. In this example, the scale factor from the blue figure to the red figure is 1.6 : 3.2, or 1 : 2.

If f(x) = 7 + 4x and g(x)=1/2x, what is the value of (f/g)(5)?

Romashka [77]

<h2>Answer:</h2>

$d. \ \boxed{270}$

<h2>Step-by-step explanation:</h2>

In this exercise we need to make a division and evaluate the new function at $x=5$ . so we have two functions, namely:

$f(x)=7+4x \ and \\ \\ g(x)=\frac{1}{2x}$

Therefore:

$f(5)=7+4(5)=27 \\ \\ g(5)=\frac{1}{2\times 5}=\frac{1}{10}$

So:

$(f/g)(5)=\frac{27}{\frac{1}{10}}=270$
