Answer:
G
Step-by-step explanation:
vertex formula = a(x-h)^2 + k
vertex is (h, k) so (-1, -4) means
y = a(x+1)^2-4
passes through (1, 8) so when x = 1 and y = 8
8 = a(1+1)^2-4 = 4a - 4
4a = 4
a = 1
Answer:
The ordered pairs for 1 and 3 are:
(1,2) (3,8)
Now use the slope formula:
(y2-y1)/(x2-x1)
(8-2)/(3-1)= 6/2 = 3

Answer:
See explanation below.
Step-by-step explanation:
First, obtain the percentage of sales tax for a sale. Say it is 5%.
Then, obtain the sale prices, for two items say they are: $25.00 and $15.00.
Add the amounts together to obtain the subtotal:
$25.00 + $15.00 = $40.00, is the subtotal.
Multiply the amount by the percentage:
$40.00 * 5% =
40 * .05 = $2.00, is the sales tax
Add the tax to the subtotal to obtain the total amount to pay:
$40.00 + $2.00 = $42.00, is the total amount to pay.
Hope this helps!! Have an Awesome Day!! :-)
