You paid $4.76 total for 7 notebooks. To figure out how much each individual notebook cost, you divide the total cost by the number of things you bought, so
Cost of One Notebook = Total Cost of Notebooks / Number of Notebooks = $4.76 / 7 = $0.68
This is the unit rate.
To buy three notebooks, you just calculate the total cost of three notebooks at this price point, so
Cost of Three Notebooks = Cost of One Notebook * 3 Notebo0ks = $0.68 * 3 = $2.04
F(x)=a(x-h)^2+k
vertex is (h,k)
f(x)=1(x-6)^2-31
f(x)=1(x-(6))^2+(-31)
h=6
k=-31
vertex=(6,-31)
1)the letter x is two times the product two Hope fully this is hopeful and you can do the same on the rest by just changing the number
2 divided by 3. Or for a fraction: 2 over 3.
