Answer:

x = -1 ; y=4

Step-by-step explanation:

1. Use the substitution method and replace the <em>y</em> on the second equation with the first equation,

2. Solve for <em>x</em> (x=-1)

3. Plug <em>x</em> into the first equation to get <em>y</em>

What is<br> |Ay|<br> in the system of linear equations below?<br><br> -8x+y=-6<br> 3x-2y=-1
Anna71 [15]

Considering the given system of equations, it is found that:

|Ay| = \left|\begin{array}{cc}-8&1\\-6&-1\end{array}\right|

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the system is:

-8x+y=-6

3x-2y=-1

In matrix form, it is given by:

\left[\begin{array}{cc}-8&1\\3&-2\end{array}\right]\left[\begin{array}{c}x\\y\end{array}\right] = \left[\begin{array}{c}-6\\-1\end{array}\right]

To find the matrix |Ay|, we replace the y coefficients of 1 and -2 by the results of -6 and -1, hence:

|Ay| = \left|\begin{array}{cc}-8&1\\-6&-1\end{array}\right|

Please help. I will give brainliest to correct answer.
Stells [14]

Answer:

The area of a square with side length of 2 inches is 4 square inches.

The area of a circle with radius 1.2 inches is:

\pi \times (1.2) ^{2}  \\  = 3.14 \times 1.44 \\  = 4.5216 \: square \: inches

That is approximately 4.5 square inches.

Hence, the area of the square (4) is less than {<} that of the circle (4.5)!
