Answer:
The answer is A. 4+y^2/2y^2
Cost of company A=monthlyfee+text=20+0.03t where t=number of texts
A=20+0.03t
company b is monthlyfee+texts=5+0.07t
B=5+0.07t
1.
c=20+0.03t
c=5+0.07t
using c for cost is confusing because we can't tell which is for which company
2.
equal, means the costs are equal so
20+0.03t=5+0.07t
minus 5 from both sides
15+0.03t=0.07t
minus 0.03t from both sides
15=0.04t
divide both sides by 0.04
375=t
the answer is 375 texts
Answer:
(-1,-1)
Step-by-step explanation:
Midpoint equation: 
= 
= 
=(-1,-1)
Use the formula and plug it in :)
First, add -5 to -14:
-3x < -9
Then, just divide!:
x < 3
Hopefully that helped! :)
The rule is 3^x.
Check: 3^1 = 3; 3^2 = 9; 3^3 = 27 and 3^4 = 81
