<span>The rule of signs is the same for multiplication and division.
Two numbers with the same sign, multiplied or divided, the answer is positive.
Two numbers with different signs, multiplied or divided, the answer is negative. </span>
The picture won’t load message me so i can answer !!
In order to know at what price the two services offered would be the same, we can actually use the process of trial and error starting from 1 onwards. The first one is 50.45 per month plus a standard fee of 60 for installation. So this will be 60+50.45x (number of days). After that. there is the other one that has free installation but charges 57.95. So it can be expressed as 57.95x. Now after trial and error with numbers as x, I came upon 8. If x is 8, then the first one will be 60+50.45 (8) = 463.6. For the second, 57.95(8) will also equal to 463.6. So the day in which the two services will charge the same is during the 8th day.
<span>Part A: How many solutions does the pair of equations for lines A and B have? Explain your answer.
The pair of equations have two solutions this is because the graph has been plotted from two systems of linear equations that the number of solutions is equal to the number of equations which is equal to 2 solutions.
</span><span>Part B: What is the solution to the equations of lines A and B? Explain your answer.
The solution to the systems of equations is found at the point where the lines intersect. This is at point (3,4); Thus the solution to the equation is x=3 and y=4. </span>
