Every other number from the first, 3rd, 5th, ..etc it adds 2 for the next number.
For the 2nd, 4th, 6th, etc term, its supposed to be 90, 78, 65, 51?
If so, It started with -12 then -13 after that -14 find the next term, all you need to do is to -15 to the current number, which is 51. then you get 36

Kipish [7]

Answer:

-600

Step-by-step explanation:

The rate of change of a function f(x) in a certain interval (x_1,x_2) is the ratio between the change of the function and the change in the value of x:

r=\frac{f(x_2)-f(x_1)}{x_2-x_1}

The rate of change of a function tells how much the value of the function is changing per change in unit of x: therefore, for a linear function it corresponds to the slope of the line.

In this problem, the function f(x) is equal to the value of the business machine in dollars, while the variable x represents the number of years.

Here we are told that the machine was purchased for

q=\$4500

while its value decreases by $600 each year, so

m=-600\$

This means that the linear function that represents the value of the machine after x years is:

y=4500-600x

Therefore, the rate of change of the function is -600.

What is a symmetric matrix?
horsena [70]

Answer:

symmetric matrix is the square matrix and it is equal to its transpose

Step-by-step explanation:

solution

a symmetric matrix is the square matrix and it is equal to its transpose

As A is symmetric matrix  then

A = A^{T}

here only square matrices will be symmetric

and matrix A is symmetric its mean its matrices have equal dimension

and every square diagonal matrix is also symmetric when all off diagonals element is zero

symmetric matrix for all indices i and j
