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:
Second one
Step-by-step explanation:
Second choice.
Second one is growing by a factor of 2 because the exponent on 2 tells me that 2 is is being repeated as a factor.
If x=0 then 15*2^0=15(1)=15 which is what we have initially.
A: 6c=75 If there were 6 movies then 6 times the cost of each movie would equal 75.
B:$12.50 We divide 75 by 6.
C: d+75=100 the cost left on the card plus 75 will equal 100.
D: $25 We subtract 75 from 100
Answer:
1) vertical
2) adjacent
Step-by-step explanation:
so, vertical is when two different numbers are congruent and adjacent is numbers next to each other but are no congruent
