podryga [215]

Answer: The lines through the pairs of points are perpendicular.

Step-by-step explanation: The lines when graphed do not have the same slope so they can not be parallel. However, when graphed the points (-3, 5) and (-1, 0) goes through the midpoint of the points (-3,1) and (2,3) meaning that the above points are perpendicular! Hope this makes sense and helps.

Can anyone help me with this math problem
Gnoma [55]

Answer:

B.)

Step-by-step explanation:

In step #1 they did the distributive property

2/5 × 15x = 6x

2/5 × -30y = -12y

The new equation would be:

6x - 12y + 10x

<em><u>Further</u></em><em><u> </u></em><em><u>Explanation</u></em>

They then combined 6x + 10x to get 16x

16x - 12y

They then factored it out to 4(4x - 3y)

Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are in
VladimirAG [237]

Answer:

The options are endless.

You do have the following requirements to the letters asked about:

c=b  (neither of these can be 0)

d=a

So here is one example:

Choose c=b=4 and d=a=9.

The functions will be:

f(x)=\frac{x+9}{4} and

g(x)=4x-9

Step-by-step explanation:

I'm going to assume my comment above.

In order for f and g to be inverse f(g(x)) has to give you x and g(f(x)) also has to give you x.

f(g(x))

f(cx-d)

\frac{(cx-d)+a}{b}

\frac{cx-d+a}{b}

\frac{cx+(-d+a)}{b}

\frac{cx}{b}+\frac{-d+a}{b}

We want this to equal x.

This means we need the following to happen:

\frac{c}{b}=1 \text{ and } \frac{-d+a}{b}=0

The first one happens when c=b assuming b isn't 0 since you can't divide by 0.

The second one happens when the top is 0 because that is the only way a fraction will output you 0 is if the numerator is 0.

So we d=a as well.

So this is what we need for f and g so that they are inverse:

f(x)=\frac{x+d}{c} since d=a and c=b

g(x)=cx-d

Let's try to see if we get x when doing both f(g(x)) and g(f(x)).

f(g(x))

f(cx-d)

\frac{(cx-d)+d}{c}

\frac{cx-d+d}{c}

\frac{cx}{c}

x

We have confirmation that f(g(x))=x.

g(f(x))

g(\frac{x+d}{c})

c(\frac{x+d}{c})-d

x+d-d

x

So f(x)=\frac{x+d}{c} and g(x)=cx-d are inverses for all choices c and d except when c is 0 since you are not allowed to divide by 0.

Your question says to insert numbers for c (=b) and d (=a).

So an example:

Let b=c=4 and d=a=9.

Let's try it:

These will be our functions with those choices for the constant variables:

f(x)=\frac{x+9}{4} and g(x)=4x-9

f(g(x))

f(4x-9)

\frac{(4x-9)+9}{4}

\frac{4x}{4}

x

We have f(g(x))=x.  Check mark, there.

g(f(x))

g(\frac{x+9}{4})

4(\frac{x+9}{4})-9

x+9-9

x
