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|

scZoUnD [109]

Answer:

Step-by-step explanation:

Janelle expanded the expression as shown below. -4(-3x + 2/7) = -12x - 3 5/7 What errors did she make?

We are given the expression:

-4(-3x + 2/7)

Solving this expression:

Expanding the brackets

-4 × -3x + -4 × 2/7

12x - 8/7

12x - 1 1/7

Help me ASAP bigger reward if you help
insens350 [35]

Answer:

x=−15+√10 or x=−15−√10

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+15)2−10=0

Step 1: Simplify both sides of the equation.

x2+30x+215=0

For this equation: a=1, b=30, c=215

1x2+30x+215=0

Step 2: Use quadratic formula with a=1, b=30, c=215.

x=−b±√b2−4ac/2a

x=−(30)±√(30)2−4(1)(215)/2(1)

x=−30±√40/2

x=−15+√10 or x=−15−√10
