Answer:

The inverse f-1(x) = (2 - x)/4 + 1.

Step-by-step explanation:

Let y = -4 /(x - 1) + 2

-4/(x - 1) = y - 2

x - 1 = (y - 2) / -4

x = -(y - 2)/4 + 1

x = (2 - y)/ 4 + 1

Now replace x by f-1(x) ( the inverse) and y by x:

f-1(x) = (2 - x)/4 + 1.

Answer:

I think the answer is D

if we use this equation to find the slope ( slope= Y2-Y1/X2-X1)

6-3= 3

2-1=1

so then you divide it and you get 3/1 or 3

mike's condo has a market value of 310000. the property in mikes area is assessed at 40% of the market value. the tax rate is 14

Svetradugi [14.3K]

If you would like to know Mike's tax, you can calculate this using the following steps:

a market value ... 310000
the property ... 40% of the market value = 40% * 310000 = 40/100 * 310000 = 124000

the tax rate ... 145.10 per 1000 of assessed valuation
145.10 ... 1000 of assessed valuation
x ... 124000 of assessed valuation
____________________________
145.10 * 124000 = 1000 * x /1000
x = 145.10 * 124000 / 1000
x = 17992.4 (Mike's tax)

The correct result would be: Mike's tax is 17992.4.

I'm studying for a test, and I can't seem to remember how to find missing coordinates. Here's one example of the question,

gulaghasi [49]

Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.
