Answer 1

Answer:

Answer:

The given system of linear equations has infinite many solutions.

Step-by-step explanation:

Given equations are

σ-2ζ=3 eqn 1

4σ-8ζ=12 eqn 2

We will use elimination method to solve the linear system

Multiplying equation 1 by 4

4(σ-2ζ) = 4(3)

4σ-8ζ=12

We can see that the both equations in the system are same i.e. we get the same equations by simplifying the equations. The graph of both equations will overlap completely.

This means that the system has infinite many solutions.

Hence,

The given system of linear equations has infinite many solutions.

Given the following exponential function, identify whether the change representsgrowth or decay, and determine the percentage rate of increase or decrease.
y = 2600(0.3)^x

Answers

Answer:

The change represents decay.The percentage decrease is 97%

Step-by-step explanation:

The change represents decay because the exponential base is less than 1. In this problem, the base is 0.3, which is smaller than 1. To find the percentage decrease, you must subtract 100% from 3%. This gives us a decrease of 97%.

A line has a rise of 3 and a run of 12. What is the slope?

Answers

Answer:

Slope = rise/run =3/12 =1/4

Step-by-step explanation:

Slope is defined as the rate of change of y wrt x.

Rate of change of y is sometimes named as rise and rate of change of x is named as run.

Given that Rate of change of y i.e. rise is 3 and rate of change of x i.e. run is 12.

Hence slope = 3/12 =0.25

the slope is
3
