Answer:
F(0)=0
Step-by-step explanation:
Because if you substitute 0 for x
F(x)=3x+5
Then calculate the product
F(0)=3(0)+5
Now remove 0 from the equation
F(0)=0
And there's your answer!! Hope this helped!!
Answer:
38
Step-by-step explanation:
Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.
So, what you need do in this question is find two fifths of 30 6 goes into 30 5 times so 2 fives is 10 so the answer is 10
