Write y=2x^2+12x+14 In vertex form

ratelena [41]

Answer:

$\large\boxed{y=2(x+3)^2-6}$

Step-by-step explanation:

The vertex form of a parabola f(x) = ax² + bx + c:

$y=a(x-h)^2+k$

(h, k) - vertex

$h=\dfrac{-b}{2a}\\\\k=f(h)$

We have the equation:

$y=2x^2+12x+14\\\\a=2,\ b=12,\ c=14\\\\h=\dfrac{-12}{2(2)}=\dfrac{-12}{4}=-3\\\\k=f(-3)=2(-3)^2+12(-3)+12=2(9)-36+12=18-36+12=-6$

Finally:

$y=2(x-(-3))^2+(-6)=2(x+3)^2-6$

A cell phone company charges $4 per GB beyond

MArishka [77]

Answer:

25GB was used that month

Step-by-step explanation:

Here, we want to calculate the GB used for the month.

Since we have $59.99 for 20GB, then the extra that brought the bill to $75.99 must have been from the beyond charges.

The extra charges is thus $75.99 - $59.99 = $20

Now, since $4 is charged as extra and we have a total of $20, the number of extra GB is thus 20/4 = 5

So the total GB for that month is 20 + 5 = 25GB

Which is an equation in point slope form of the line that passes through the points (7 -8) and has a slope of -3

Nataly [62]

Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13
