Answer:
Step-by-step explanation:
for the given equation,
using rules of equation and inverse operations as isolating x on one side of equation,
interchanging sides of equation we get,
Answer:
Step-by-step explanation:
Simple interest = 
End of first year = 650+19.5 = $669.50
End of second year = 669.50+19.5 = $ 689
End of third year = 689+19.5 = $708.50
End of fourth year = 708.50 +19.5 = $ 728
End of fifth year = 728 +19.5 = $747.50
Since the two equations equal y, set them equal to each other.
x-1=-2x+5
From there, solve for x.
First get x on one side, by using the addition property of equality.
x-1=-2x+5
3x-1=5
Isolate x by adding 1.
3x=6
Lastly get x all by itself by dividing each side by 3.
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1
Any questions or anything you would like me to clarify, feel free to ask :)
The populations is all of the beavers at the park and the sample is the 10 that he randomly chose. A population means the total amount, so it wouldn’t make sense that it would be 10. A sample is a portion of the entire population, so 10 would be the right answer since it is only a portion of the entire population. 31 does not work because it is the data that is found using the sample of 10 beavers.
Answer:
The correct set of hypotheses is
: d=80 degrees
: d>80 degrees
Step-by-step explanation:
The weatherman claims that the average temperature during July in Chattanooga is 80 degrees or less. To test this claim, following hypotheses need to be taken:
Let d be the the average temperature during July in Chattanooga, then
: d=80 degrees
: d>80 degrees
