the arrows on the end of the line means it continues
both the domain and the range for this graph is negative infinity to infinity
Answer:
8x^2+3x
Step-by-step explanation:
What I read is 2x+8x^2-4x+5x
combining like terms means putting the terms that have the same variable part together
8x^2 is the only one that doesn't have any terms like it as far as the variable part
so 8x^2+2x-4x+5x
We just need to figure out 2-4+5 which is -2+5=3
So the answer is 8x^2+3x
F(1) is saying the value of x is 1
Look at the graph where x is 1 and find the y value of where the line is.
At x = 1, the line is at y = 1 ( there is actually a dot showing you the location.
The answer is 1
Answer:
-35.148
I don't know if you need to round the answer or not
Step-by-step explanation:
The <em>correct answer</em> is:
6.6 years.
Explanation:
Since he goes from making $28,000 per year to $14,000 per year, he will lose $14,000 each year that he works part-time. He intends to do this for 2 years; this will be a loss of $14000(2) = $28,000.
We will add the cost of his degree to this: 28,000+5,000 = $33,000.
He will be making $33,000 per year when he graduates. This is 33000-28000 = 5000 more per year than he made before.
To find out how many years it will take him to recover his investment, we divide the amount he loses, 33,000, by the extra amount he will make per year, 5000:
33000/5000 = 6.6
