Step-by-step explanation:

Vertex: (3,2)

Point: (13,8)

The equation form is

h = 3

k = 2

y = 8

x = 13

Plug in the values into the form..

Simplify and solve for a..

Plug a into the equation..

Hope this helped you!

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make
