Hello,
Answer D
x²/(25)²+y²/15²=1
If she has 15 dollars and saves 5.25 each week it would take her 6 weeks.
5.25*6=31.50
31.50+15=46.50
So in total 6 weeks.
hope this helps!
Answer:
B. It is decreasing.
Step-by-step explanation:
The X value is the sideways one, and the direction of the line in between the two points listed is going downwards. The value of the line in the graph is decreasing.
Answer:
[6.5,-7.25]
Step-by-step explanation:
Given the partitioning ratio as 3:1
#Find the length of the x-coordinate and multiply by the ratio:
x length=9--1=10
=>
#We subtract 2.5 from the x-max to get the point=9-2.5=6.5
#Find the length of the y-coordinate and multiply by the ratio:
x length=-9--2=-7
=>
#We subtract -1.75 from the y-max to get the point=-9--1.75=-7.25
Hence, the coordinates that partitions the segment into a ratio of 3 to 1 is [6.5,-7.25]
