What is the value of n in the equation 3n + 2(n + 2) = 9n + 12?
Elan Coil [88]

Answer:

3n+2(n+2)=9n+12

3n+ 2n + 4 = 9n + 12

3n+ 2n +4 - 4 = 9n + 12 - 4

3n + 2n - 9n = 12 - 4

5n - 9n = 8

<u>-4n </u> = <u>8</u>

-4. -4

n. = - 2

A parabola is given by the equation y = x^2 + 4x + 4.
insens350 [35]
Y = x² + 4x + 4.. Since the coefficient of x² =1, is positive, then this parabola opens upward & has a minimum.


Its axis of symmetry is = -b/a = -4/1 = 4 (so x=4)

1) When x=4, y= 4²+4(4)+4 => y=36 so the VERTEX has a minimum is at (4,36) 

2)FOCUS.: To be able to calculate the focus, rewrite the equation in a standard form: y-k =a(x-h)² & y = x² + 4x + 4 could be written y=(x+2)², this means that k=0 & h=-2.
Now p being the distance between the VERTEX & the FOCUS, we apply the formula (x-2)² = 4P (y-k) , but k=0 & h=2 then (x-2)² = 4P(y-0) then P =1/4

3) DRECTRICE : y=k-P = 0-1/4 ==> y=-1/4 is the directrix

State which of the following sets of ordered pairs represent a function.
stich3 [128]
A function is an equation that has only one answer for y for every x. This means that:

Set A and Set C are functions because their y values don’t repeat.

Set B is NOT a function because the 2 in the y values repeats twice.

Hope I helped!
