What is the vertex of the function f(x) = x2 + 12x?

Sophie [7]3 years ago

We can start by figuring out the axis of symmetry.

y = x² + 12x = x (x + 12)

So roots are x = -12 or 0

Therefore axis of symmetry is x   =   (-12 + 0) / 2   =   -6

We got x-coordinate of vertex. Now plug in x=-6 to solve for y.

y = (-6)² + 12(-6)   =   36 - 72   =   -36

Therefore vertex is (-6, -36).

A game decreased in price by 2/3. After the reduction it was priced at £13. What was the original price of the game?​
Archy [21]

Answer:

x = 39

Step-by-step explanation:

Based on the given conditions, write: x=\frac{13}{1-\frac{2}{3}}

Find common denominator and write numerators above common denominator: x=\frac{\frac{13}{3-2} }{3}

Calculate the sum or difference: x=\frac{\frac{13}{1} }{3}

Divide the fraction by multiplying its reciprocal: x=13*3

Calculate the product or quotient: x=39

Answer: x=39

Divide 30 by it's half, add the half of 18 that has been divided by the half of the half of 12 after been divided by half.
WARRIOR [948]

Answer:

We want to divide 30 by it's half.

The half of 30 is 30/2 = 15

then we have: 30/15 = 2

Now we want to add the half of 18, that has ben divided by the half of the half of 12 hafter been divided by half.

The half of 12 is 12/2 =  6

the half of the half of 12 is 6/2 = 3

now, we wanto to divide the half of 18 by that number.

The half of 18 is 18/2 = 9

then we have 9/3 = 3

and we wanted to add this to the number previous found:

2 + 3 = 5
