For x values 1 unit either side of the vertex, the value of y is 2 more than it is at the vertex.
a = 2
_____
More formally, The graph appears to go through the point (4, 1). Substituting these values for (x, y) in the equation, we get
1 = a(4-3)² -1 . . . . substitute for x and y
2 = a . . . . . . . . . . add 1 and simplify
Answer:
(a) 10×8
(b) 31×9
Step-by-step explanation:
We have given that
(a) 81 - 1
We have to write this in form of product of two integers
We know the algebraic equation 
As 81 -1 can be written as 
So 
(b) We have given 400 - 121
We have to write this in form of product of two integers
We know the algebraic equation
As 81 -1 can be written as 
So 
Answer:
Step-by-step explanation:
12x - 4 = 56
add 4 to each side
12x = 60
divide each side by 12
x = 5
