Which ratio is not equivalent to the other three? A 2 3 B 12 15 C 18 27 D 6 9
finlep [7]

Answer: B= 12 15

Step-by-step explanation:

The given ratios are

A) 2 3= 2: 3  already in its simplest form

B)  12 15 =12:15 Changing to its simplest form, we divide both by 3 giving us           4:5

C)  18 27 =18: 27  Changing to its simplest form, we divide both numbers by 9 giving us =2:3        

D)6 9=6:9  Changing to its simplest form, we divide both by 3 giving us  

       2:3

Therefore the ratio not equivalent to other three is 12:15

Find the rule and the graph of the function whose graph can be obtained by performing the translation 3 units left and 2 units d
Vsevolod [243]

Let

g(x)--------> the translation of the function f(x)

we know that

the rule of the translation is

3 units left and 2 units down

that means

(x,y)-------> (x-3,y-2)

so

In the function f(x) the point (0,0) is equal at the point  (-3,-2) in the function g(x)

therefore

the function g(x) is equal to

g(x)=f(x+3)-2

g(x)=(x+3)^{3} -2

<u>The answer is</u>

a) the rule of the translation is (x,y)-------> (x-3,y-2)

b) The graph in the attached figure
