Answer:
x = -3, y = 1
Step-by-step explanation:
To find the value of x and y, find the determinant of original matrix, which would be 21.
Then, substitute the value of x with the solutions to the equations and find the determinant of that matrix, which is -63.
Cramer's rule says that Dx ÷ D is the value of x. So, -63 ÷ 21 = -3.
So, the x-value is -3.
You can find the determinant of the y-value in the same way, and you'll find out that y = 1.
Hope this helped! :)
Answer:
Mildred is correct because she distributed 5 correctly
Step-by-step explanation:
We cannot tell exactly which solution goes with which student, but we believe you are saying ...
Mildred’s Solution:
5 (Negative 2 and one-fourth) = 5 (negative 2 minus one-fourth)
= negative 10 minus StartFraction 5 over 4 EndFraction
= negative 11 and one-fourth
This solution describes the correct distribution of 5. Whoever it belongs to gave the correct solution.
