7) A. A variable is an unknown value, and x is unknown. Constants are known values so they cannot have X in it.
8)A again for the same reason as number 7
Answer:
the answer would be 1/15, or approximately 0.067.
Step-by-step explanation:
Answer:
3/-2 or -1.5
Step-by-step explanation:
remember to find slope using a graph the equation is rise over run so it goes up 3 and the decreases or moves towards the left 2
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.
