How do I find the ratio?
Len [333]
You got it correct!
To get from 52 to 13, you divide by 4. And Vis versa, to get from 13 to 52, you multiply by 4. Considering they don't tell you which is the original, the only answer that is either 4 or 1/4 is F

Hope this helps!

Find (f/g)(x) f(x)=4x+1 g(x) =3x-4
mash [69]
Your answer is very close to being correct; however, the true answer is actually \frac{4x+1}{3x-4} without any parenthesis needed around the fraction. Notice how there is no (x) at the end.

Use the given parent function f(x)=|x| to graph g(x)=|x+2|-4. use the ray tool and select two points to graph each ray. ​
marin [14]

Shown in the attached figure

<h2>Explanation:</h2>

The absolute value function is a function that takes the shape of a V. The pattern of the absolute value function is:

f(x)=\mid x \mid

So we need to use this function in order to obtain:

g(x)=\mid x+2 \mid -4

Recall that to translate a function vertically, we use the following rule:

g(x)=f(x)+k \\ \\ \bullet \ If \ k>0 \ the \ graph \ of \ f(x) \ is \ translated \ k \ units \ up \\ \\ \bullet \ If \ k

And to translate a function horizontally, we use the following rule:

g(x)=f(x+c) \\ \\ \bullet \ If \ c>0 \ the \ graph \ of \ f(x) \ is \ translated \ c \ units \ to \ the \ left \\ \\ \bullet \ If \ c

Since:

c=2>0 \  and \ k=-4

Then:

<em>g(x) is the translation of f(x) 2 units to the left and 4 units down</em>

Determine if this relationship forms a direct variation. Verify your answer.
leva [86]

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form y/x=k or y=kx

so


we have

a) for x=1 y=0.50--------> y/x=0.50/1------> 0.50

b) for x=2 y=1--------> y/x=1/2-------> 0.50

c) for x=3 y=1.50--------> y/x=1.50/3-----> 0.50

d) for x=5 y=2.50--------> y/x=2.50/5----> 0.50

the value of k is equal to 0.50

so

<span>the relationship forms a direct variation. </span>

the equation is

y=0.50*x


Verify

for x=1

y=0.50*(1)------> y=0.50-----> is correct


for x=2

y=0.50*(2)------> y=1.00-----> is correct


for x=3

y=0.50*(3)------> y=1.50-----> is correct


for x=5

y=0.50*(5)------> y=2.50-----> is correct
