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 question is not fully visible but what u want to do is group them subtract/add what u can and then factor it out
Step-by-step explanation:
Answer:
672 square inches
with area, multiply the side(s) by themselves for a single number, or their following numbers for more than 2 numbers.
Example
- 18in x 18in = 324 square inches
- 4in x 2in x 5in x 9in = 360 square inches
hope this helps!
50% is equal to the so we can easily divide 9 by 2 to get your answer 4.50 there is no hundreths for it is a clean divide (4.5×2=9)
