heather writes the equations below to represent two lines drawn on the coordinate plane. –6x 18y = 0 4x – 12y = 20 after applyin
g the linear combination method, heather arrived at the equation 0 = 60. what conclusion can be drawn about the system of equations? the equation has no solution; therefore, the system of equations has no solution. the equation has a solution at (0, 60); therefore, the system of equations has a solution at (0, 60). the equation has infinite solutions; therefore, the system of equation as infinite solutions. the equation has a solution at (0, 0); therefore, the system of equations has a solution at (0, 0).
The equation has no solution; therefore, the system of equations has no solution.
Explanation:
When solving a system of equations, after we combine the equations, if we find that there is no solution, that means that there is no solution to the entire system of equations.
<span>In this example the equation has no solution. This is because, in algebra, the variables are what is solved for. Here, through the combination method, Heather has determined that 0 = 60, which is not true. Zero cannot equal a number other than itself; additionally there are no variables that were solved for in this equation. By this it is meant that "x" is not given a value and "y" is not given a value. These two values would be used for coordinates to plot the line on a graph</span>
<span>Similar means their sides have the same ratio but don't have to be the same length. So if two rectangles are similar with a scale factor of 2 then the ratio of their areas would be 4:1</span>
In order to find a percentage, you are supposed to divide the amount of how much someone has picked by the total amount (in this case pizza's). Here is how I got 80%,
