Which of the following equations is an example of inverse variation between the variables x and y?
2 answers:
Answer:
C
Step-by-step explanation:
A and B are examples of direct variations because there is a nonzero constant k in each such that y=kx. A's k=1/12 while B's k=12.
D is not a direct or inverse variation because of the plus/minus constant.
C is an inverse variation because it has form y=k/x where k is nonzero. This k=12.
Answer:
C
Step-by-step explanation:
The equation representing inverse variation is
y = 
← k is the constant of variation
The only equation that fits this description is
y = 
→ C

Answer:
100
Step-by-step explanation:
200+3qq+400+q3q
200+3q²+400+3q²
3q²-3q²+400-200
q²=200
q²=200/2
q²=100
Answer:
f(x) is y so the x=16 because 4*4=16
Create a system of equations
x + y = 123
5x + y = 343
I use substitution
y = 123 - x
5x + 123 - x = 343
4x + 123 = 343
4x = 220
x = 55
Plug in
x + y = 123
55 + y = 123
y = 68
Check
5x + y = 343
5(55) + 68 = 343
275 + 68 = 343
343 = 343
