Amodel train has a scale of 1 in : 2 ft. if the model train is 9 in tall, then how tall is the real train? a. 5 ft b. 18 ft c. 11 ft d. 2 ft

the solution is 12x-6y

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
