Answer:
Step-by-step explanation:
Standard form:
Vertex form:
(h, k) is the vertex
x is the coordinate of the vertex
To find x use the formula:
a=1
b=-2
c=-6
Substitute:
Substitute x in equation:
h=1
k=-7
Substitute h, and k into the vertex formula:
suppose Tomas buys a total of 30 baseball and football cards in week 5 . how many of each would he have to buy to keep the same
proportional relationship?
1 answer:
Answer:
- 18 baseball cards
- 12 football cards
Step-by-step explanation:
The only relationship shown in the table is in week 1, where the ratio of baseball to football cards is ...
baseball : football = 9 : 6
In week 1, the total of these numbers is 15. You want the total in week 5 to be 30, double the total in week 1. So, Thomas needs to purchase double the numbers he purchased in week 1:
- 18 baseball cards
- 12 football cards

This table came from another question you posted, a question with no content other than the table. The blue numbers are blanks in the original table that have been filled in so as to keep the same 3:2 proportion in each week. They appear to have no bearing on this question.
