Write an equation given the he vertex form and a point. vertex(3,2)and pass through the point(-1 -2)

Step-by-step explanation:

The vertex form of a quadratic equation is: y = a(x - h)² + k,     where

Input the vertex (3, 2) and the point (-1, -2) into the equation to solve for "a":

Now, input the vertex and the a-value into the equation:

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
