Step-by-step explanation:
all you have to doe is type Ex:4 into the calculator and you should get your answer.
So since the vertex falls onto the axis of symmetry, we can just solve for that to get the x-coordinate of both equations. The equation for the axis of symmetry is
, with b = x coefficient and a = x^2 coefficient. Our equations can be solved as such:
y = 2x^2 − 4x + 12: 
y = 4x^2 + 8x + 3: 
In short, the vertex x-coordinate's of y = 2x^2 − 4x + 12 is 1 while the vertex's x-coordinate of y = 4x^2 + 8x + 3 is -1.
I think it’s b
have a nice day
For every 3 cups of peanuts there are 2 cups of chocolate
9/3 = 3 so 3*2 = 6
For 9 cups of peanuts there are 6 cups of choclate
2y - 3x = 4
2y = 3x + 4
y = 3/2*x + 2
y = kx + b ==>
k = 3/2 = 1,5
