Answer:
27
Step-by-step explanation:
To evaluate f(8) substitute x = 8 into f(x)
f(8) = 
× 8² - (
× 8 + 3)
= × 64 - (2 + 3)
= 32 - 5
= 27
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.
You multiply 12x8.3 and get the answer 100
Answer:
Commutative Property
Step-by-step explanation:
The property of multiplication that is being demonstrated is known as Commutative Property. This property basically shows that when multiplying two numbers the actual order in which they are multiplied does not matter and does not affect the result at all. For example, the in this scenario to get the total number of oranges we have to multiply the number of bags by the number of oranges in each bag, but whatever way we do this they equal the same
2 bags * 3 oranges per bag = 6 oranges
3 bags * 2 oranges per bag = 6 oranges
Therefore,
2 * 3 = 3 * 2
