20; make both equations equal so whatever you plug in for x will be the same
2(4x+10)=8x+k
8x+20=8x+k
k=20
Answer:
See below.
Step-by-step explanation:
"Part A:
(1,5.5)
(2,5)
(3,4.5)
(4,4)
(5,3.5)
(6,3)
Every hour (x value) I subtracted 0.5 from the candle height (y value) since it burns at 0.5 inches per hour.
Part B:
Yes, this is a function because there is a constant relationship between the input and the output.
Part C:
Yes, this will continue to be a function because there is still a constant relationship, even though its different than the first one.
(1,5.7)
(2,5.4)
(3,5.1) ect."

Well D. represents -1/4 because there are 4 parts that make up -1, and D. is right before 0, so that makes it -1/4.
With my same explanation as before, you have gotten the second one correct; well done! =D
Well, I hope I helped! =D
Answer:
X^2+y^2=45
Step-by-step explanation:
Since the equation of a circle is (x – h)^2 + (y – k)^2 = r^2, we can substitute the h and k in which are both 0 and we get x^2+k^2=r^2. Using the Pythagorean theorem to find the radius, we get r^2=45 or r=sqrt(45). So the equation for the circle is x^2+y^2=45.
