Rewrite the system of equations in matrix form.

This system has a unique solution
so long as the inverse of the coefficient matrix
exists. This is the case if the determinant is not zero.
We have

so the inverse, and hence a unique solution to the system of equations, exists as long as m ≠ -4.
Standard form means, move the variables to the left-hand-side and leave the constant all by herself on the right-hand-side, usually sorting the variables, so"x" goes first.
now, there's a denominator, we can do away with it, by simply multiplying both sides by the denominator, so let's do so,
✅
Step-by-step explanation:


10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
Area = 1/2(diagonal) * √4*side^2 - diagonal^2
Area = 1/2(16)*√(4*17^2 - 16^2)
Area = 8 * √(4*289-256)
Area = 8 *√900
Area = 8 * 30
Area = 240 m^2
