i don't really get the part after the (-4,-6) , what did u write there
Base from the graph the intersection of the line is at 12 months. so this is the time where the cost of the two internet provider is equal. this can be solve by equating the two and solve for t.
<span>C(t) = 180 + 10t , C(t) = 25t
180 + 10t = 25t
180 = 25t - 10t
180 = 15t
t = 12

Answer:
-4
Step-by-step explanation:
Given vertex, the axis of symmetry is x = h.
Answer:
D
Step-by-step explanation:
The equation is 1/2+3/x=3/4, it is still solvable
the equivalent of the equation is (1.x+2.3)/2.x = 3/4, or (x+ 6)/2.x=3/4, this last can be solved as follow: 4.(x+ 6) = 2x.3, 4x+ 24 = 6x, so 24=6x-4x=2x, and when 2x= 24 , it means x=24/2 =12, finally the equation is solvable because x=12 is a solution
