The vertex form of the equation of a parabola is y = (x - 4)2 + 22. What is the standard form of the equation?
ELEN [110]
To write an equation in standard form, move each term to the right side of the equation and simplify.
y=ax^2 + bx + c
y=ax^2+bx+c
Solve for

valentinak56 [21]

Answer:

Freezers made up \frac{6}{25} = 24% of the appliances sold in January.

Step-by-step explanation:

We have that:

10 + 8 + 12 + 12 + 8 = 50 parts were sold in January.

Freezers made up what part of the appliances sold in January?

12 of those were freezers, so:

\frac{12}{50} = \frac{6}{25} = 0.24

Freezers made up \frac{6}{25} = 24% of the appliances sold in January.
