He lost $30 bc
Guy stole $100
Guy gave back $70
Owner gives hue $30 !
If that makes any sense ♀️
L(t)=9-0.5t
t=time in hours,
L(t)=length of candle at time t
(A) substitute t=1,2,3,4,5,6 respectively to get
(1,8.5)
(2,8)
(3,7.5)
(4,7)
(5,6.5)
(6,6)
(B) it is a function because none of the x-values duplicate, (nor the y-values).
(C) If the rate changes to 0.45 "/hr, the relation is still linear.
All linear function with finite slope are functions.
Answer:
D
Step-by-step explanation:
So we have the equation:
![x^2-6x+58=0](https://tex.z-dn.net/?f=x%5E2-6x%2B58%3D0)
And we want to solve for x.
We can solve it by completing the square.
First, subtract 58 from both sides:
![x^2-6x=-58](https://tex.z-dn.net/?f=x%5E2-6x%3D-58)
Divide the b term by 2 and square it:
![(-6)/2=-3\\(-3)^2=9](https://tex.z-dn.net/?f=%28-6%29%2F2%3D-3%5C%5C%28-3%29%5E2%3D9)
So, add 9 to both sides:
![(x^2-6x+9)=-58+9](https://tex.z-dn.net/?f=%28x%5E2-6x%2B9%29%3D-58%2B9)
On the left, the perfect square trinomial pattern. Add on the right. So:
![(x-3)^2=-49](https://tex.z-dn.net/?f=%28x-3%29%5E2%3D-49)
Take the square root of both sides:
![x-3=\pm \sqrt{-49}](https://tex.z-dn.net/?f=x-3%3D%5Cpm%20%5Csqrt%7B-49%7D)
The square root of -49 is 7i:
![x-3=\pm 7i](https://tex.z-dn.net/?f=x-3%3D%5Cpm%207i)
Add 3 to both sides:
![x=3\pm 7i](https://tex.z-dn.net/?f=x%3D3%5Cpm%207i)
So, our answer is D.
And we're done!
