Answer:59
Step-by-step explanation:
Use the distance formula to find the distance between points A and B. The distances between points A and C and between points B and C should be the same (half of the distance between A and B).
Sqrt((x1-x2)^2 + (y1-y2)^2)
So the answers are Yes, Yes, and No
You'd want to use a vertical line test.
1st image: Every vertical line cuts the graph at at most one point
2nd image: The vertical line x = 1 cuts the graph at more than one point
3rd image: The vertical line x = 1 cuts the graph at 2 points
4th image: The vertical line x = -2 cuts the graph at 2 points
Hence, graph 1 (1st image) is a function.
I think its B. 7
Its less than 15 and all the others.
It is best to use the discount first because the more value, higher percent.
Discount First:
4.00*.5 = $2.00 TOTAL
$2.00-$1.00 = $1.00 GRAND TOTAL
Discount After:
4.00-1 = $3.00 TOTAL
3*.5 = $1.50 GRAND TOTAL
You would save 50 cents
