Answer:
y = 
Step-by-step explanation:
Standard equation in point slope form is :
y-y_0 = m(x-x_0) +c
where m = slope = -1/2
(x_0,y_0) is the point from which the lines passes through = (5,-3)
We get the equation as,
y-(-3) = -1/2(x-5)
y+3 =
(x-5)
y = 
y = 
Hence, m= -1/2 and c = -1/2
Required equations is:
y = 
Answer:
100.00
Step-by-step explanation:
x=number of months until the costs are the same
50 + 20x = 25 + 30x
25 = 10x
x = 2.5 months
50 + 2.5(20) =$100.00
In order to know the answer for this one, let us analyze the whole problem.
Given that the store already lose $100 stolen by the guy, this guy also bought a merchandise worth 70$, and gets a change of $30. The merchandise was paid, but still, the store lost $100, and then an additional $30, for giving it back to the guy. So the total lost of the store would be $130. Hope this answer helps.
