Answer:
2k
Step-by-step explanation:
Let k is the ratio between two variables or y = kx
when x double, means: y = k (2x) = 2kx quantity y will change with a ratio 2k
The domain is all of the possible x values, and there are none less than -3 in this case, so the answer is B, which shows that x must be greater than or equal to -3.
200+50+4 I think is the answer
If x is negative, then 10-x must be positive.
for example: let's say x=-1. then 10-(-1)=11
