The correct answer is 10.
In order to evaluate any composite function, you need to first put the value in for the inside function. In this case f(x) is on the inside along with the number 3. So, we input 3 in for x in f(x).
f(x) = 2x + 1
f(3) = 2(3) + 1
f(3) = 6 + 1
f(3) = 7
Now that we have the value of f(3), we can stick the answer in for the outside function, which is g(x).
g(x) = (3x - 1)/2
g(7) = (3(7) - 1)/ 2
g(7) = (21 - 1)/2
g(7) = 20/2
g(f(3)) = 10
Answer:
Ben drove faster
Step-by-step explanation:
<h2>BEN:</h2>
350 miles / 6.5 hours = 53.84 miles per hour
<h2>MARCIE:</h2>
520 miles / 12.25 hours = 42.44 miles per hour
53.84 is faster than 42.44 therefore Ben is faster.
Answer:
For part A
10.08x=y
Step-by-step explanation:
252/25=10.08
x=number of hours=25
y=how much earned=252
10.08(25)=252
Start by going in the order of decimals and what ever you end at, put this number on top
142857/<span>100000
And then you simplify it to the smallest numbers and you have your answer. It can't be simplified so it is just:
</span>142857/<span>100000</span>
Given:
The recipe calls for
cup of strawberries for each gallon of lemonade.
Tia has 6 cups of strawberries.
To find:
The number of gallons of lemonade she can make.
Solution:
We have,
cup of strawberries for = 1 gallon of lemonade
cup of strawberries for =
gallons of lemonade
=
gallons of lemonade
=
gallons of lemonade
cup of strawberries for =
gallons of lemonade
=
gallons of lemonade
=
gallons of lemonade
Therefore, 9 gallons of lemonade she can make by using 6 cups of strawberries.
