Answer:
Tamara's example is in fact an example that represents a linear functional relationship.
- This is because the cost of baby-sitting is linearly related to the amount of hours the nany spend with the child: the more hours the nany spends with the child, the higher the cost of baby-sitting, and this relation is constant: for every extra hour the cost increases at a constant rate of $6.5.
- If we want to represent the total cost of baby-sitting in a graph, taking the variable "y" as the total cost of baby-sitting and the variable "x" as the amount of hours the nany remains with the baby, y=5+6.5x (see the graph attached).
- The relation is linear because the cost increases proportionally with the amount of hours ($6.5 per hour).
- See table attached, were you can see the increses in total cost of baby sitting (y) when the amount of hours (x) increases.
The answer is C.
5c+2w= 12
(5 x 2 )+(2 x1)=12
10 + 2 = 12
7c + 4w=15
(7x1) + ( 4x2) = 15
7 + 8 = 15
Hope this helps. :)
Found this on google to help you out but it states “ Find the first derivative of a function f(x) and find the critical numbers. Then, find the second derivative of a function f(x) and put the critical numbers. If the value is negative, the function has relative maxima at that point, if the value is positive, the function has relative maxima at that point.”
Answer:
Finding a dime, 5/10
Finding a penny, 2/9
Step-by-step explanation:
add up the total number of coins, 10, and put the number of dimes over it
5/10
add up the total number of coins, 10, and subtract a dime, so there is 9 coins, but 2 pennies so 2/9
