Step-by-step explanation:
It's the vertex form of a quadratic equation of
The vertex is at (h, k).
k is minimum or maximum for value of h.
k - its value of y for x = h.
We have
[tex]k=2(8^2)-32(8)+56=2(64)-256+56=128-256+56=-72[/tex
Answer:
The expression 16.78d + 49 represents the amount Rita spent at the mall.
If she bought 3 itens, Rita spent $99.34.
Step-by-step explanation:
Expression:
First store: 16.78d + 23
Second store: 26
Total: 16.78d + 23 + 26 = 16.78d + 49
Then estimate how much Rita spent if she bought 3 items.
Now, we have that d = 3. So
16.78*3 + 49 = 99.34
If she bought 3 itens, Rita spent $99.34.
