Answer: The correct answer is: [D]: "8" .
Step-by-step explanation:f y varies inversely with x; then y = k/x ; with "k" being the "constant" in this equation.
You can find the constant by substituting the values given: x = 16, f(x) = y = 2 ;
So, f(x) = y = 2 = k/16 ;
→ 2 = k / 16 ;
Solve for the constant; "k" ;
Multiply EACH SIDE of the equation by "16"
→ 16* (2) = (k / 16) * 16 ;
→ 32 = k ;
↔ k = 32 ;
As such, we can write the equation:
y = k/ x ; as:
→ y = 32/ x ;
Since we are given: "x = 4" ; Plug in that value; and solve for "y" ;
y = 32/4 = 8 .
y = 8 .
y = f(x) ;
So; f(x) = 8 ; which is: Answer choice: [D]: "8" .

Answer:
-9
Step-by-step explanation:
Adding a negative 3 is the same as subtracting 3, so if you do -6 - 3 you get -9
The answer is 12.6 %.
60% = 60 / 100 = 0.6
60% of 21
= 60% * 21
= 0.6 * 21
= 12.6
Answer:
GCF is 4ab
And the expression will be: 4ab ( 3a^2+2ab-5b^2)
Step-by-step explanation:
Factor the GCF :
12a^3b + 8a^2b^2-20 ab^3
We need to find the common terms that are common in each of the term given above
12,8 and 2 are all divisible by 4
a is common in all terms and b is also common in all terms,
So, GCF is 4ab
Taking 4ab common
12a^3b + 8a^2b^2-20 ab^3=4ab ( 3a^2+2ab-5b^2)
