Answer:
D. $53.76.
Step-by-step explanation:
20% = 0.20 as a decimal.
Price before Sales Tax = 64 - 0.20*64
= $51.20
Adding 5% sales tax we get
52.20 + 0.05*51.20
= $53.76 (answer).
Positive correlation.
Zero is x increases y stays the same
Negative is both decrease
Answer:
Exponential
374.4
Step-by-step explanation:
This function is not linear. You can tell because the f(x) values do not increase by adding the same number each time.
163.84 + 81.83 = 245.67
245.67 + 122.88 = 368.64
The rate of change is different each time.
The average rate of change from x = 2 and x = 6 is the difference in y values over the difference in x values.
1866.24 - 368.64 = 1497.6
6 - 2 = 4
1497.6 / 4 = 374.4
Answer:
9-4t
Step-by-step explanation:
Answer:
3+4p+8t
Step-by-step explanation:
We have been given an expression:
3+2(2p+4t)
We will simplify the equation:
Firstly, we will open the parenthesis by multiplying it with the 2 given outside of the parenthesis we get:
3+4p+8t
Since, we have two variables so it can not be further solved therefore,
This is the maximum simplification of the given expression.
