Answer:
your answer is C.
Step-by-step explanation:
The system of the equation doesn't give the solution at (-3, -6).
<h2>Given to us</h2>
<h3>Equation 1,</h3>
-4x+y = 6
solve for y

<h3>Equation 2,</h3>
5x-y =21
substitute the value of y in equation 2,

Substitute the value of x in equation 2,

We can see that the solution of the two equations is at (27, 114). Also, it can be verified by plotting the line on the graph.
Hence, the system of the equation doesn't give the solution at (-3, -6).

Step-by-step explanation:
We can rule out A and D because of the area.
The area of a cube with side length 1/4 is 1/64, times 840, is 13 1/8
The area of a cube with side length 1/2 is 1/8, times 420, is 52 1/2
Step 1- Set up the equation.
Step 2- Divide the first digit.
Step 3- Divide the first two digits.
Step 4- Enter the first digit of the quotient.
