Which equation is a linear function?

Answers

im like 60% sure its y=x

Answer:

y = x

Step-by-step explanation:

In general ,A linear function has the form y = ax + b

so ,the functions :

y = √x

y = x²

y = x³

don’t meet the requirements of the definition

therefore none of them is linear.

but y = x is a valid choice (just put a = 1 and b = 0  in the expression y = ax + b)

Step-by-step explanation:

Order the numbers from smallest to largest, then cross one number off until you have one or two numbers left.

If there is an EVEN number of numbers(like this one): there will be two numbers left, therefore you add those two numbers together, then divide by two.

If there is  an ODD number of numbers: there will be one number left, therefore that is your answer!

f(x) = 3x + 2 and g(x) = x + 5

g[f(x)] =

A. 3x + 7
B. 3x + 17
C. 4x + 7

Answers

Answer:

A

Step-by-step explanation:

g[f(x)]=g(3x+2)=3x+2+5=3x+7

The function defined by g[f(x)] is equal to  3x+7. hence the correct option is A.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

We have been given the function as

f(x) = 3x + 2 and g(x) = x + 5

We need to find the function defined by g[f(x)]

g[f(x)] = g(3x+2)

g[f(x)] =3x+2+5

g[f(x)] = 3x+7

Therefore, the function defined by g[f(x)] is equal to  3x+7. hence the correct option is A.

About 150,000 people live in a 8-mile radius of a city's town hall. Find the population density in people per square mile. Round your answer to the nearest whole number.

Answers

Answer:

747  people per square mile

Step-by-step explanation:

population of  city's town hall = 150,000

Radius of  city's town hall = 8 mile

area of any circular shape is given by [tex]\pi r^2[/tex].

r is the radius of circle.

p

Area of city's town hall = [tex]\pi r^2= 3.12*8^2 = 3.14*64 = 200.96[/tex]

Population density for any place is ratio of population of that place to area of that place

Thus

Population density for city's town hall = population of  city's town hall /Area of city's town hall

Population density for city's town hall =  150,000/200.96

Population density for city's town hall= 746.42  people per square mile.

Population density for city's town hall  Rounded  to the nearest whole number is 747  people per square mile.

Do the following points belong to the graph of the function f(x)=13−5x ? (-2,23)

Answers

Answer:

Yes!

Step-by-step explanation:

When we have problems like this we just plug them in. We take the -2 and we multiply it by the -5 to get a positive 10. We then add that to the +13 and it equals 23, so it works!

Yes!
You plug in the -2 into x and the 23 into f(x).

f(23)= 13-5(-2)
f(23)= 13+10
f(23)= 23
