<u>Answer</u>:
8x^5y^7
<u>Step by step explanation</u>

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

<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]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-8%261%5C%5C3%26-2%5Cend%7Barray%7D%5Cright%5D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D-6%5C%5C-1%5Cend%7Barray%7D%5Cright%5D)
To find the matrix |Ay|, we replace the y coefficients of 1 and -2 by the results of -6 and -1, hence:

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
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
18x18 = 324
(16x26)/2 = 208
324 + 208 = 532
answer: 532 m^2
