3 x 4x = 12x
3 x -5 = -15 12x - 15 = 45
+15 +15
12x = 60
divide by 12
x = 5
Answer:
Esther is right. Take the cash today
Step-by-step explanation:
The value of money tends to decrease due to inflation. With GH¢1000 now, she can invest and work to earn more herself.
The answer would be 9.2 . if you use pythagorean’s theorem.
Success can be measured in three ways:
1. Patience. You must be patient especially if you are still new to business. There will be a time when your sales are not good.
2. Perseverance. But no matter how hard it is, you must find ways in order for your business to grow.
3. Good customer service. When you achieved successfully in business, it will be reflected back to your customers whether they have been treated well, their wants are answered and they are contented with your product
Answer:
is the required matrix form.
Step-by-step explanation:
Here, the given system of equation is:
5 x + 4 y = -14,
3 x + 6 y = 6
In a system of equation, the matrix for is given as
AX = b
Here, A = Co-efficient Matrix, X = Variable Matrix and B = Constant Matrix
Considering the given system:
Co-efficient Matrix(A) = ![\left[\begin{array}{ccc}5&4\\3&6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%264%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D)
Variable Matrix(X) = ![\left[\begin{array}{ccc}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D)
Constant Matrix(b) =![\left[\begin{array}{ccc}-14\\6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-14%5C%5C6%5Cend%7Barray%7D%5Cright%5D)
Hence, the combined matrix form of AX = b is
![\left[\begin{array}{ccc}5&4\\3&6\end{array}\right]\left[\begin{array}{ccc}x\\y\end{array}\right]=\left[\begin{array}{ccc}-14\\6\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5%264%5C%5C3%266%5Cend%7Barray%7D%5Cright%5D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-14%5C%5C6%5Cend%7Barray%7D%5Cright%5D)
