Standard form

Step-by-step explanation:

The equation is in standard form

Step-by-step explanation:

Vertex form would look something like this: y = a(x+b)(x+c)

Factored form would look like vertex form

The relationship is a quadratic so ignore the rest of the answers.

Therefore the equation is in standard form.

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
