Step-by-step explanation:

1. 200 = 10h

320 =

320x10 / 200

= 16h

2. 1.5 = 50m

x = 150 m

150x1.5 / 50

= 4.5cm

3. 4$ = 40balls

x = 100balls

100x4 / 40

= $10

The answer to the first one is 16 hours. This is because it is 20 pages per hour, then when you divide 320 by 20, you get 26.
Hope this helps. I was to lazy to do the others.

Find the inverse function in slope-intercept form (mx+b):
BabaBlast [244]

Answer:

y= 3- x/3

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=9−3x so it becomes x=9−3y.

Now, solve the equation x=9−3y for y. You would just need to leave y alone so you divide by 3 on both sides (NOT negative 3. Just 3.)
