Answer:
1.75 yards
Step-by-step explanation:
1.5+3.25=4.75
6.5-4.75=1.75
The answer is $328,000. Since the investment is $82,000 every seven years, and there is 28 years. If you divide 28 by 7 you get 4. Then you multiply 82,000 by 4 to get your answer : $328,000.

Answer:
B. f(g(x)) = -10x + 8
Step-by-step explanation:
When evaluating f(g(x)), substitute what g(x) is in place of g(x).
So instead of
f(g(x))
the function would be:
f(-5x + 6).
Now all you have to do is evaluate this.
To evaluate this function, substitute the value inside the f(x) for all instances of x in the equation.
f(x) = 2x - 4
f(-5x + 6) = 2(-5x + 6) - 4
f(-5x + 6) = -10x + 12 - 4
f(-5x + 6) = -10x + 8
Therefore, f(g(x)) = -10x + 8.
