Answer:
domain: (-∞,∞)
range: (-∞,∞)
Step-by-step explanation:
You need to convert this into a linear equation (y=mx+b)
So we add 2y and divide by 2 to get y by itself
that gives us 5x-2=y
If you pictures this graph in your head you'll see that the domain and range are all real numbers

Answer:
.
Step-by-step explanation: The first answer is c. 7+3w, because the puppy already weighs 7 ounces. Since the puppy didn't end up losing those pounds, then you would add instead of subtract. Since the puppy gains 3 ounces a week, you would multiply the 3 ounces by the number of weeks that pass by. So, if one week passes, the puppy gains three ounces. Add that to the original 7 ounces, then after one week, the puppy weighs 10 ounces.
The second answer would be a. 22 ounces, because if you use the previous formula (x=7+3w), then you would plug 5 in for w. This would give you 7+3(5). 3x5=15 and 15+7=22. therefore, x=22 ounces.
