Answer:
a is equal to 22 because 11 times 2 is 22
Answer:
Multiply the 8 by 5
Step-by-step explanation:
8÷1/5
Copy dot flip
8 * 5/1
40
Answer:
8
Step-by-step explanation:
The equation of the parabola can be represented as

for some constant a.
Since the coefficient of x² is 2, a = 2, so

So, the answer is 8.
Using linear functions, it is found that the two plans cost the same for 5000 minutes of calling.
<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0.
For Plan A, the cost is of $25 plus an additional $0.09 for each minute of calls, hence the y-intercept is
, the slope is of
, and the function is:

For Plan B, the cost is of $0.14 for each minute of calls, hence the y-intercept is
, the slope is of
, and the function is:

The plans cost the same for x minutes of calling, considering that:





The two plans cost the same for 5000 minutes of calling.

The given expression is

We just have to divide by 2

<h2>Hence, the solution is all real numbers less than 10.</h2>
