8n = -3m + 1; n = -2, 2, 4
bogdanovich [222]

I am assuming you want to solve for m in each case

8n = -3m + 1

8(-2) = -3m + 1

-16 = -3m + 1

-3m = -17

m = \frac{17}{3}

8(2) = -3m + 1

16 = -3m + 1

-3m = 15

m = -5

8(4) = -3m + 1

32 = -3m + 1

-3m = 31

m = \frac{31}{3}

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent th
Alla [95]

Answer:

S = \frac{b}{m}

Step-by-step explanation:

Given

Speed = s

Required

Determine the expression for s

The speed is calculated as:

Speed = \frac{Number\ of\ books}{Time}

Substitute S for speed

S= \frac{Number\ of\ books}{Time}

Let the number of books be b and the time be m.

The expression becomes

S = \frac{b}{m}

Hence, the expression for the scenario is:

S = \frac{b}{m}

What is the inverse of the function f(x) = 2x + 1?
BaLLatris [955]

Answer:

f^{-1} = \frac{x-1}{2}

Step-by-step explanation:

f(x) = 2x+1

<em>Replace it with y</em>

y = 2x+1

<em>Exchange the values of  x and y</em>

x = 2y+1

<em>Solve for y</em>

x = 2y+1

<em>Subtracting 1 from both sides</em>

2y = x-1

<em>Dividing both sides by 2</em>

y = \frac{x-1}{2}

<em>Replace it by </em>f^{-1}

So,

f^{-1} = \frac{x-1}{2}

Why is the number 6 scared of the number 7?
Lady_Fox [76]
This is a well known joke:

Why six afraid of seven? Because seven ate nine!

It is supposed to be a "word game" where instead of writing eight, the authour wrote ate, which sound the same but means something different.


Hope it helped,

Happy homework/ study/ exam!
