Nesterboy [21]

Correction is the question: 6\frac{1}{2}%% = 6.5%

Answer:

Amount to be repaid is $335798.833

Step-by-step explanation:

Amount of loan = $332,200

Rate of interest = 6.5%

time =  2months = 2/12 = 1/6 years

The amount of interest is simple interest

SI = \frac{P * R * T}{100}

    =\frac{ 332200 * 6.5 *1 }{100 * 6}

    = $3598.833

Final amount to be repaid = 332200+ 3598.833

                                            = $335798.833

Pls help me with this:((((((((​
Natalija [7]

Answer:

1) D: All of the above.

2) A: No solution

3) B: One solution

Step-by-step explanation:

<h3>1. The systems of linear equations can be solved through the following methods: </h3>

Graphing method: Using the slope and y-intercepts of each equation to plot points and graph the lines to see whether the given system has a <u>point of intersection</u> as a solution.

Elimination method: this involves either <u>adding</u> (when the coefficients have opposite signs) or <u>subtracting</u> (when the coefficients have the same sign).  

Substitution method: involves solving for one of the variables of either equations, and substituting the values of that expression into the other linear equation in the system.

Therefore, the correct answer is Option D: All of the above.

<h3>2. Graph of Parallel Lines:</h3>

Given the graph of parallel lines, which means that they will never have a point of intersection. Therefore, the given systems of linear equations have no solution. Therefore, the correct answer is Option A: No solution.

<h3>3. Graph of Two Intersecting lines</h3>

Given the graph of two non-perpendicular intersecting lines, it means that they have <u>one point of intersection</u> that represents the <em>solution</em> to the given system.

Therefore, the correct answer is Option B: One solution.
