Answer:

The inverse is 1/3 (x+1)

Step-by-step explanation:

y = 3x-1

Exchange x and y

x = 3y-1

Solve for y

Add 1 to each side

x+1 = 3y-1+1

x+1 = 3y

Divide each side by 3

(x+1)/3 = 3y/3

1/3(x+1) =y

The inverse is 1/3 (x+1)

Answer:

see below

Step-by-step explanation:

m = (y2-y1)/(x2-x1)

= (90-80)/(0-1)

= 10/-1

=-10

The slope is -10 ft/s

This means the height decreases 10 ft for every second that passes

This is not proportional because it has to go through the point (0,0)

m = (y2-y1)/(x2-x1)

= (1000-0)/(3-0)

= 1000/3

=1000/3

The slope is $1000/3

This means the 1000 dollars is sold every 3 days

This is proportional because it goes through the point (0,0) and has a constant slope

Which of the following numbers is irrational? Please help!!

Nastasia [14]

Irratonal numbers can't be written as a/b where a and b are integers and b≠0

so if it can be written in form a/b then it is not irrational

$\sqrt{36}=6=\frac{6}{1}$ , it's rational

1/5 is rational

$\sqrt{60}=2\sqrt{15}$ it's irrational because we can't simplify the square root further

6.3=6.3/1=63/100, rationanl

answer is $\sqrt{60}$ is irrational
