For example, in the composition of(f g)(x) = f(g(x)), we need to replace each x found in f(x), the outside function, with g(x), the inside function. Step 3: Simplify the answer. Examples – Now let's use the steps shown above to work through some examples. Example 1: If f(x) = –4x + 9 and g(x) = 2x – 7, find(f g)(x).
The answer is d + 0.25(d - 22) = 10.75
d - the amount of dollar coins
q - the amount of quarters
It is given: d + q = 22
The quarter is $0.25, therefore:
d + 0.25q = 10.75
Now, we have the system of equations:
d + q = 22
d + 0.25q = 10.75
According to the first equation:
d + q = 22 <span>⇒ q = 22 - d</span>
We will replace q in the second equation:
d + 0.25q = 10.75 ⇒ d + 0.25(22 - d) = 10.75
Lin's tour costs 5*14 +50 = 70 +50 = 120. Max's tour costs 120.
Neither tour costs less. Both have the same cost.
It is just 4 x 4 for each and everyside
With a SSS you’ll only see the little tick marks but on a SAS you’ll see a tick, angle indication, then another tick
