ANSWER
The multiplication, CA is defined, and its dimension is 3×2
EXPLANATION
Matrix A is a 2x3 matrix.
Matrix C is a 3×2 matrix.
The product of the two matrices , CA, is defined if and only if the inner product of their dimension are the same.
![CA = (2 \times 3)(3 \times 2)](https://tex.z-dn.net/?f=CA%20%3D%20%282%20%5Ctimes%203%29%283%20%5Ctimes%202%29)
The inner products are the same.
Hence the matrix multiplication, CA is defined and its dimension is the outer products.

Answer:
11.1%
Step-by-step explanation:
17/153= 0.111 x 100= 11.1%
Answer:
?=19
x=30
Step-by-step explanation:
5/6x - 1/5x = 19
5(5/6x) - 6(1/5x) = 19
25/30x-6/30x=19
19/30x=19
19x=19(30)
19x=570
x= 570/19
x=30
Answer:
Solution of an Equation in Two Variables - Generally, a two-variable system solution is an ordered pair that makes BOTH equations valid.
Graph of an Equation in Two Variables - In the Ax + By = C form, linear equations with two variables will appear, and the resulting graph is always a straight line.
Linear Equation - Any equation that can be written in shape is a linear equation. Ax+b=0, 0.0 Where the real numbers are a and b, and x is a vector.
Linear Function - Those whose graph is a straight line are linear functions. The following form has a linear function. F(x) = y = a + bx.
I can't add a drawing right now, but I help these help!!
Answer:
The relation is ![y = -1.5x](https://tex.z-dn.net/?f=y%20%3D%20-1.5x)
Step-by-step explanation:
x and y are directly proportional:
This means that the equation is given by:
![y = ax](https://tex.z-dn.net/?f=y%20%3D%20ax)
In which a is the multiplier that relates these two variables.
x= -4, y =6
We use this to find a. So
![y = ax](https://tex.z-dn.net/?f=y%20%3D%20ax)
![6 = -4a](https://tex.z-dn.net/?f=6%20%3D%20-4a)
![a = -frac{6}{4}](https://tex.z-dn.net/?f=a%20%3D%20-frac%7B6%7D%7B4%7D)
![a = -1.5](https://tex.z-dn.net/?f=a%20%3D%20-1.5)
So
The relation is ![y = -1.5x](https://tex.z-dn.net/?f=y%20%3D%20-1.5x)
