Answer:
i think it is f(x)= 10m+0.10s
x= number text messages send
m= months
for example: if you send 200 messages and were in the plan for 3 month the function will go like this;
f(x)= 10(3)+0.10(200)
=30+20
= $50
X + 10 = -13
-13 - 10 = x
-23 = x
CHECK
-23 + 10 = -13
-13 = -13!
Answer:

Step-by-step explanation:
Sides of the figure = n = 7
<h3><u>Formula for measuring the interior angles of a polygon:</u></h3>
(n - 2)×180
Where n is the number of sides in the polygon
So,
<h3><u>Measure of interior angles in the figure:</u></h3>
= (n - 2) × 180
= (7 - 2) × 180
= 5 × 180
= 900
