Step-by-step explanation:
a. What is the total cost (startup fee and monthly charge) to use the cell phone plan for 1 month?
answer for a: <em>$95 + $55 = $150</em>
b. Is there a proportional relationship between time and the cost of the cell phone plan?
answer for b: <em>There is a proportional relationship between time and the cost of the cell phone plan because each month of time that passes, your phone will be charged $55. We know this because every month of Han's cell phone plan costs $55. </em>
c. What is the total cost for x months? (Write an equation for the situation.)
answer for c: <em>95 + 55x = y</em>
Answer:
i) The augmented matrix for this system is
ii) The reduced row echelon form
iii) The set of solutions are
= -692/65
= 423/130
= -493/65
Step-by-step explanation:
i) An augmented matrix for a system of equations is a matrix of numbers in which each row represents the constants from one equation (both the coefficients and the constant on the other side of the equal sign) and each column represents all the coefficients for a single variable.
We have the following system of equations:
Here is the augmented matrix for this system.
ii) To find the reduced row echelon form of
you must:
- Divide row 1 by 4
- Subtract row 1 multiplied by 2 from row 2
- Add row 1 to row 3
- Divide row 2 by 13
- Add row 2 multiplied by 1/2 to row 1
- Subtract row 2 multiplied by 11/2 from row 3
- Multiply row 3 by −2/5
- Add row 3 multiplied by 3/2 to row 1
- Subtract row 3 multiplied by 1/2 from row 2
The answer is
iii) The set of solutions are
= -692/65
= 423/130
= -493/65
There was a son a dad and his dad. I know this is confusing but there is a son who has a dad and his dad is there as well. So the dad's dad would be the littlest one's grand-dad
