Answer:

reflect across x axis: (x,-y)

reflect across y axis: (-x,y)

reflect across y=x: (y,x)

reflect across y= -x: (-y,-x)

90 cc rotation: (-y,x)

180 rotation: (-x,-y)

270 cc rotation: (y,-x)

Step-by-step explanation:

reflect across x axis: (x,-y) - x coor stays same and only y coor becomes negative

reflect across y axis: (-x,y) - x coor becomes negative and y coor stays the same

reflect across y=x: (y,x) - both coordinate switch places, no signs are changed

reflect across y= -x: (-y,-x) - both coordinates switch places and the signs are switched to the opposite sign of the original number

90 cc rotation: (-y,x) - opposite of the original y coor and both coordinates switch place (same as 270 clockwise)

180 rotation: (-x,-y) - both coordinates stay in there original place but with the opposite values of the original value

270 cc rotation: (y,-x) - both coordinates switch places and the x values is the opposite of the original value (same as 90 clockwise)

*to find the third columns answer all you have to do is plug in the given x and y values into the coordinate rule

1) Inverse function: f^{-1}(x)=g(x)=\frac{x+4}{3}

2) f(1) = -1, g(-1) = 1

3) f(g(x))=g(f(x))=x

Step-by-step explanation:

1)

In this first method, we want to find the inverse function of f(x).

The original function is:

f(x) = 3x-4

We rewrite it as

y=3x-4

We swap the name of the variables:

x=3y-4

Adding +4 on both sides:

x+4=3y-4+4\\x+4=3y

And dividing by 3 on both sides:

y=\frac{x+4}{3}

which is identical to g(x):

g(x)=\frac{x+4}{3}

2)

In this second method, we want to use the output of one function as input to the other function, and show that the output value is equal to the imput value.

We start using the function

f(x)=3x-4

We choose x=1. We find:

f(1)=3(1)-4=3-4=-1

Now we use this output value as input in the function

g(x)=\frac{x+4}{3}

Substituting x=-1,

g(-1)=\frac{-1+4}{3}=\frac{3}{3}=1

So, the final output value (1) is equal to the input value (1).

3)

Here we want to verify that the two are inverse functions by showing that

f(g(x))=x

We have

f(x)=3x-4\\g(x)=\frac{x+4}{3}

Substituting g(x) into f(x),

f(g(x))=3g(x)-4 = 3(\frac{x+4}{3})-4=(x+4)-4=x

Viceversa, we want to show that

g(f(x))=x

Substituting g(x) into f(x), we get

g(f(x))=\frac{f(x)+4}{3}=\frac{(3x-4)+4}{3}=\frac{3x-4+4}{3}=\frac{3x}{3}=x

So, the two functions are one the inverse of the other.

How many groups of 60 equal 300
hichkok12 [17]
Okay, ask yourself this : how many times does 6 goes into 30?

6 and 1 = 6
6 and 2 = 12
6 and 3 = 18
6 and 4 = 24
6 and 5 = 30

6 goes into 30 a number of 5 times. And so that means that :

60 and 1 make 60.
60 and 2 make 120
60 and 3 make 180.
60 and 4 make 240
60 and 5 make 300

FIVE (5) groups of 60
make 300.

I need a little bit of help

The symbols make it hard to solve, but it's still doable.

m = melon

c = coconut

f = flamingo

s = shirt

m - c + 1 = 4

f + f = c

m + s = 15 - 3

8 - m = m


Using the last equation, we can solve for a value of m.

Add m to both sides.

8 = 2m

Divide both sides by 2.

m = 4

The value of m is 4, and so we have one variable done.

m + s = 15 - 3

Replace value of m with 4.

4 + s = 15 - 3

Simplify right side.

4 + s = 12

Subtract 4 from both sides.

s = 8

The value of s is 8, and so we have two variables done.

m - c + 1 = 4

Replace value of m.

4 - c + 1 = 4

Combine like terms.

5 - c = 4

Subtract 5 from both sides.

-c = -1

Multiply all terms by -1.

c = 1

The value of c = 1.

We can now solve the final equation.

f + f = c

Replace value of c.

f + f = 1

Combine like terms.

2f = 1

Divide both sides by 2.

f = 0.5

We have all four variables solved for.


<h3>M, or melon, is equal to 4.</h3><h3>S, or shirt, is equal to 8.</h3><h3>C, or coconut, is equal to 1.</h3><h3>F, or flamingo, is equal to 0.5</h3>
