Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cell phone bill for x minutes. Using points (230, 17.45) and (370, 19.55):
For 150 minutes:
y = 0.015(150) + 14 = 16.25
For $21.50:
21.50 = 0.015x + 14
x = 500
It would take 500 minutes for the cost to be $21.50.

Answer:
-11
Step-by-step explanation:
m²+12q
= (5)² + 12(-3)
= 25 -36
= -11
<u>We have to look for the pattern in the numbers</u>, so we can figure out what the next term in the sequence is !
It looks like,<u> each number is multiplied by 2!</u>
7 × 2 = <em>14 </em>
14 × 2 = <em>28 </em>
So, what's next?
28 × 2 = ?
The next term in the geometric sequence is ... 56!
I hope I helped :)
Comment if you have any confusion !
So, the area of a circle is a=pi r^2
so do that and get a=pi(4)
and since the circle touches the edge of the rectangle, the rectangle is 4 cm tall, so 4*8 is 32 and pi(4) is about 12.56, so 32-12.56 is 19.44, and I believe that is the answer. (19.4)
