Answer:
Multiply the decimal for the percent of tax by the purchase price, then add the amount of tax to the price to find the total price.
Step-by-step explanation:
Sales tax is an amount added to a price to get the total.
We multiply by the decimal for the percent; this means we divide the percent by 100 before we multiply.
Once we multiply, this gives us the amount of sales tax. We add this to the price of the item to get the total purchase price.
For this case the main function is:
f (x) = x ^ 2
We are going to apply the following transformations:
Vertical translations
Suppose that k> 0:
To graph y = f (x) + k, move the graph of k units up.
We have then:
f (x) = x ^ 2 + 5
Horizontal translations
Suppose that h> 0
To graph y = f (x + h), move the graph of h units to the left.
We have then:
f (x) = (x + 1) ^ 2 + 5
Answer:
f (x) = (x + 1) ^ 2 + 5

Answer:
+- 5 and +- 3
Step-by-step explanation:
qn 2:
4r² = 91 + 9
4r² = 100
r² = 25
r = +- 5
qn 3:
4r² = 29 + 7
4r² = 36
r² = 9
r = +- 3
Answer:

Step-by-step explanation:
So we have the equation:

First, subtract 3 from both sides:

Definition of absolute value:

Divide both sides by 6 for both equations:

And we're done!
