I think it might be easier to understand if i change decimals to fractions, so lets start ;)
$15.249=15\frac{249}{1000}$
$15.3=15.300=15\frac{300}{1000}$
$15.05=15.050=15\frac{50}{1000}$
$15.009=15\frac{9}{1000}$
$15.25=15.250=15\frac{250}{1000}$

denominators are the same so now you only have to compare numerators (biger numerator = greater fraction)

so:

$15\frac{9}{1000}$

it means that:

$15.009$

If f(x) = 7x+6 and g(x)=8x-4 find f(g(-2))

sp2606 [1]

Answer:

$f(g(-2))=-134$

Step-by-step explanation:

So we have the two functions:

$f(x)=7x+6\text{ and } g(x)=8x-4$

And we want to find f(g(-2)).

First, let's find g(-2):

$g(-2)=8(-2)-4$

Multiply:

$g(-2)=-16-4$

Subtract:

$g(-2)=-20$

Now, substitute:

$f(g(-2))=f(-20)$

Now, find the value of f(-20):

$f(-20)=7(-20)+6$

Multiply:

$f(-20)=-140+6$

Add:

$f(-20)=-134$

So:

$f(g(-2))=-134$

And we're done!
