I don't know what to do but I think it is #1
This is a good question... but is there multiple choice, i want to know if my answer matches
Answer:
Increasing on it's domain
because the slope is positive.
The domain and range are both all real numbers, also known as
.
Step-by-step explanation:
All domain really means is what numbers can you plug in and you get number back from your function.
I should be able to plug in any number into 3x+2 and result in a number. There are no restrictions for x on 3x+2.
The domain is all real numbers.
In interval notation that is
.
Now the range is the set of numbers that get hit by y=3x+2.
Well y=3x+2 is a linear function that is increasing. I know it is increasing because the slope is positive 3. I wrote out the positive part because that is the item you focus on in a linear equation to determine if is increasing or decreasing.
If slope is positive, then the line is increasing.
If slope is negative, then the line is decreasing.
So y=3x+2 hits all values of y because it is increasing forever. The range is all real numbers. In interval notation that is
.
The age of the van owned = 12 years
The age of the truck owned = 29 years
Step-by-step explanation:
Here, the given question is INCOMPLETE.
Laura takes very good care of her vehicles. She owns a blue van and a red truck. Although she bought them both new, she has owned the truck for 17 years longer than she has owned the van. If the sum of the ages of the vehicles is 41 years, how old is the van and how old is the truck?
Let us assume the number of years Laura has owned the van = S years
So, according to the question:
The number of years she has owned truck = S + 17 years
Now, Sum of the age of ( Truck + Van) = 41 years
⇒ (S + 17 years) + (S years) = 41 years
or, 2 S + 17 = 41
or, 2 S = 4 1 -1 7 = 24
or, S = 24/2 = 12 years
or, S = 12 years
Hence the age of the van owned = 12 years
The age of the truck owned = S + 17 = 12 + 17 = 29 years
17.6 is your answer
Hope this helps!!
