What is the rate of change of the function?

Answers

Answer 1

Answer:

Answer:

Option A

Step-by-step explanation:

The given function is a linear function therefore rate of change of this function will be the slope of the given line.

Since this line passes through two points ( 0,1 ) and ( 0.5 0 )

the slope of the line = $((y-y'))/((x-x'))$

slope = $((1-0))/((0-0.5))$

= ( -2 )

Therfore, Option A will be the answer.

Answer 2

Answer:

The rate of change of function is,

m = - 2

We have to given that,

A function is shown in figure.

Since, The rate of change of linear function is slope of line.

Here, Two points on the line are (1, - 1) and (0, 1)

Since, The equation of line passes through the points (1, - 1) and (0, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-1)) / (0 - 1)

m = 2 / - 1

m = - 2

So, The rate of change of function is,

m = - 2

What are two different methods you can use to figure out what 34% of 120 is? (Explain both methods and show your setup of each) Do not solve

Answers

You can use the proportion $(is)/(of)$ or $(part)/(whole)$ = $(percent)/(100)$ , where you fill in what you know, crossmulitply, and solve for x. You can also write it as an equation, where of=mulitply and is=equal to, and the percent is expressed as a decimal. Your two different equations would be .34x120=x and $(x)/(120)$ = $(34)/(100)$

the answer would be 40.8. simply u take 34 multiply by 120 the u divide the answer by 100 to 40.8
