What is the equation for the line of symmetry for the graph of the functiony=-4x^2+6x-8?

C.
x=3/4

The axis of symmetry of y=ax²+bx+c is -b/(2a)

given

y=-4x²+6x-8
a=-4
b=6

axis of symmetry is -6/(2*-4)=-6/-8=6/8=3/4

answer is C

The time that elapses for the reactant molecules to break their bonds and make new bonds to give rise to the products is known as

Reaction rates

Explanation:

Reaction rates is time that elapses for the reactant molecules to break their bonds and make new bonds to give rise to the products.

Reaction rate is the speed at which chemical reactions occur. It is the change in concentration of a reactant or product per unit time. The rate of reaction changes with time significantly. Reaction rate is measured based on the rate of disappearance of a reactant or appearance of a product with increasing reaction time.
