Answer:
5 $20 bills and 7 $10 bills
Step-by-step explanation:
You need to have 12 bills, and their values must add up to $170. Start with a guess, and adjust the guess until you find the answer.
The total number of $20 bills and $10 bills must be 10.
I made a table below. I started with a guess and kept adjusting it.
Number of Number of Total
$20 bills $10 bills Value
8 ($160) 4 ($40) $200 Value is too high.
6 ($120) 6 ($60) $180 Value is close
5 ($100) 7 ($70) $70 Correct value
Answer: 5 $20 bills and 7 $10 bills
I think this is the answer
=(3h+61)
Answer:
{2, 6, 14}
Step-by-step explanation:
Using f(x) = 4x + 6 with a domain of {-1, 0, 2 }, find the range.
To get the range, we will substitute the values of the domain into the given function as shown;
when x = -1
f(-1) = 4(-1)+6
f(-1) = -4+6
f(-1) = 2
when x = 0
f(0) = 4(0)+6
f(0) = 0+6
f(0) = 6
when x = 2
f(2) = 4(2)+6
f(2) = 8+6
f(2) = 14
Hence the required range are {2, 6, 14}
