The question is an illustration of systems of equations, where 2 or more equations model a particular subject.

The system of equations is:

\mathbf{j + p = 75}

\mathbf{660j + 450p = 675}

Let:

j represents jogging

p represents power yoga

She wants to spend 75 minutes.

This is represented as:

\mathbf{j + p = 75}

The total calories to burn out is 675.

This is represented as:

\mathbf{660j + 450p = 675}

Hence, the system of equations is:

\mathbf{j + p = 75}

\mathbf{660j + 450p = 675}

A football team wants to by a football. The football costs $51. There are 11 members of the team. How much will each of the team members contribute to be able to purchase the football if they had $29 already.

Solution: Let the amount each team member contributes be x, then
11x + 29 ≥ 51
11x ≥ 51 - 29
11x ≥ 22
x ≥ 22/11
x ≥ 2

I.e. each team member must contribute at least $2 for them to be able to buy the football.

Please help!! <br> Solve the system using an augmented matrix. Show all work
marishachu [46]

Answer:

<em>The solution of the system is:  x=2, y=5</em>

Step-by-step explanation:

The given system of equations is.......

-x-3y=-17\\ \\ 2x-6y=-26

So, the augmented matrix will be:   \left[\begin{array}{cccc}-1&-3&|&-17\\2&-6&|&-26\\\end{array}\right]

Now, we will transform the augmented matrix to the reduced row echelon form using row operations.

<u>Row operation 1 :</u>  Multiply the 1st row by -1. So..........

\left[\begin{array}{cccc}1&3&|&17\\2&-6&|&-26\\\end{array}\right]

<u>Row operation 2:</u>  Add -2 times the 1st row to the 2nd row. So.......

\left[\begin{array}{cccc}1&3&|&17\\0&-12&|&-60\\\end{array}\right]

<u>Row operation 3:</u>  Multiply the 2nd row by -\frac{1}{12}. So.......

\left[\begin{array}{cccc}1&3&|&17\\0&1&|&5\\\end{array}\right]

<u>Row operation 4:</u>  Add -3 times the 2nd row to the 1st row. So........

\left[\begin{array}{cccc}1&0&|&2\\0&1&|&5\\\end{array}\right]

Now, from this reduced row echelon form of the augmented matrix, we can get that x=2 and y=5

So, the solution of the system is:  x=2, y=5
