What is the vertex of the equation, y= -3x^2+2x-7?

Genrish500 [490]

Given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 ), then

The x-coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = - 3x² + 2x - 7 is in standard form

with a = - 3, b = 2 and c = - 7, hence

$x_{vertex}$ = - $\frac{2}{-6}$ = $\frac{1}{3}$

Substitute this value into the equation for y-coordinate

y = - 3 ( $\frac{1}{3}$ )² + 2 ( $\frac{1}{3}$ ) - 7

= - $\frac{1}{3}$ + $\frac{2}{3}$ - $\frac{21}{3}$ = - $\frac{20}{3}$

vertex = ( $\frac{1}{3}$ , - $\frac{20}{3}$ ) → A

Amir has spent the last three months saving money for a $1,400 computer in his local electronics store. So far he has saved $1,2

Fiesta28 [93]

25% off of $1400 equal: 1400 + .25 = 350, so 1400 - 350 = 1050
So now the computer with 25 % off is $1050.
tax 7%, means 1050 + .07 = $73.50 (sales tax charge)

Total computer with 25% off plus 7% tax equal:

$1050 + 73.50 = $1,123.50

Amir has saved $1200, so he has enough money to purchase the computer.
