Answer:
2. 4a+2c = 5000
4. a + c = 1600
Step-by-step explanation:
Answer:
the slope of the line=0/6
Step-by-step explanation:
you can use the formula `y-y/`x-x, where (-8,5)=(x,y) and (-2,5)=(`x,`y)
5-5/-2--8
5-5/-2+8
0/6
Therefore, the slope of the line=0/6
The service plans are illustrations of linear equations
It will take 125 minutes for the plans to have the same cost
<h3>How to determine the number of minutes</h3>
From the question, we have the following parameters
<u>Service plan 1</u>
- Monthly fee = $16
- Charges = $0.15 per minute
<u>Service plan 2</u>
- Monthly fee = $21
- Charges = $0.11 per minute
So, the linear equations for both plans are:
When the plans cost the same, we have:
Collect like terms
This gives
Solve for x
Hence, it will take 125 minutes for the plans to have the same cost
