Neither one of the slopes are going to be minus. It means you are travelling backwards in time, which is wonderful if you are a sci-fi fan, but not so good if you are Sharon. A and D has Sharon going from 70 to 0. That can't be happening so both are wrong.
Now you have to decide between B and C. The intersection point has Sharon going upwards until she is 20. She started out at 70. The graph has John starting at 70. That's not right.
So we've eliminated A,D and now C.
The answer must be B. They meet when Sharon is 90 and John is about 22.5 which is what it should be.
The answer is f(x)=x²+2x when evaluated with -3 gives you the value of 3
If you input: 1/0.00000001 in a calculator, the result will be a very large number
so as you get closer to zero, the result of 1/x larger until it becomes infinite (or undefined as some people like to call it) at 1/0
Answer:
$1.99 is more expensive.
Step-by-step explanation:
Given:
One type of lace edging cost $0.80 per foot
Another type of lace edging cost $1`.99 per foot.
We need to find which is more expensive.
In $0.88 where one's place is 0.
In $1.99 where one's place is 1.
By comparing the one's place obviously $1.99 more expensive.
Hope you will understand the concept.
Thank you.
