Find the (LCD) 5/6 and 11/8

eduard

Answer:

24

Step-by-step explanation:

First we write the first few multiples of 6 (the first denominator) :

6,12,18,24,30

Now we write the first few multiples of 8 (the second denominator) :

8,16,24,32,40

As we can see 24 is the lowest number that appears in both list.

Therefore it is the LCD of 5/6 and 11/8

Find g(x), where g(x) is the translation 5 units right and 12 units up of f(x)=3x+5.

Rasek [7]

$f(x)=3x+5\\\downarrow/5\ units\ right/\\f(x-5)=3(x-5)+5\\\downarrow/12\ units\ up/\\f(x-5)+12=3(x-5)+5+12\\\\g(x)=3(x-5)+17=3x-15+17=3x+2\\\\Answer:\ \boxed{g(x)=3x+2}$

NO LINKS!!! This is NOT MULTIPLE CHOICE!!!

aleksley [76]

Answer:

Given equation: $y=(x+1)^2-2$

The function is a <u>quadratic function</u> in <u>vertex form</u>: $y=a(x-h)^2+k$

<u>Translations</u>

For $a > 0$

$f(x+a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units left}$

$f(x-a) \implies f(x) \: \textsf{translated}\:a\:\textsf{units right}$

$f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}$

$f(x)-a \implies f(x) \: \textsf{translated}\:a\:\textsf{units down}$

Parent function: $f(x)=x^2$

<u>Translations</u>

Translated 1 unit left: $f(x+1)=(x+1)^2$

Then translated 2 units down: $f(x)-2=(x+1)^2-2$

Therefore, translate the parent function by <u>1 unit left</u> and <u>2 units down</u> to produce the given equation.
