Answer:
vertex form
Step-by-step explanation:
y= -3(x-5)^2+7
This equation is written in vertex form
y = a(x-h)^2 +k
The vertex is (h,k)
Answer:
11
Step-by-step explanation:
since 30÷45 = 2/3 then
The space taken by a small book is equal to
the space taken by 2/3 a large book.
…………………………………………………
<u><em>Calculating the number of large book corresponding to 23 small books</em></u> :
= 23×(2÷3) + 3
= 18.333333333333 (large book)
Then ,Kevin can pack the shelf with (at most) : 30 - 19 = 11 more large books

Answer:
2 positive * 1 negative = negative
2 negative * 1 positive = positive
Step-by-step explanation:
one positive and 2 negative
(+ * -) * - =
positive times negative = negative * negative = positive
(+ * -) * - = +
now if we change the order by putting parenthesis
+ *( - * -)
negative time negative = positive
+ * (+) = positive
the result is positive
The result does not change because of where we put the parentheses.
- * + * + =
negative times positive = negative
negative * positive= negative
- * + * + = negative
The order does not matter
