When reflecting over the line y = x, we swap the positions of x and y.

The rule is [tex](x,y) \to (y,x)[/tex]

Side note: this process is useful when it comes to finding the inverse. This is because the inverse undoes the original function.

Answer:

3

Step-by-step explanation:

Step 1: Define

c = 9

f(c) = √c

Step 2: Substitute and Evaluate

f(9) = √9

f(9) = 3

Answer:

3

Step-by-step explanation:

C=9

The square root of C is the same as the square root of 9

3 x 3 = 9, so the square root of C is 3. C(C)=9

If your teacher wants you to factor, then use the difference of squares rule

9x^2 - 4

(3x)^2 - 2^2

(3x-2)(3x+2)

Answer:

Width = 22ft  Length = 48ft

Step-by-step explanation:

Length = 2(w) + 4

I personally first picked a random number (20) and I got 128, so I knew I had to pick a larger number.

I skipped up to 22 and this is what I did.

W = 22(2) <--(Since there are two width sides) = 44

L = 2(w) + 4

L = 2(22) + 4

L = 44 + 4 = 48

48(2) <--(Since there are two length sides) = 96

96 + 44 = 140

Hope this helps!

Answer:

x intercept

(x;y=0)

y=492-16.4x

0=492-16.4x

-492=-16.4x /÷(-16.4)

30=x

(30;0)

y intercept

(x=0;y)

y=492-0

y=492

(0,492)

Solving for x

Answer:

x = -6

Step-by-step explanation:

4(1 - x) + 3x = -2(x + 1)

~Distribute both sides

4 - 4x + 3x = -2x - 2

~Combine like terms

4 - x = -2x - 2

~Add x to both sides

4 = -x - 2

~Add 2 to both sides

6 = -x

~Divide -1 to both sides

-6 = x

Best of Luck!

I took a quiz with this question.

Step-by-step explanation:

Answer:

The correct option is;

Exactly 3 of the 12 soccer players practiced for at least 75 hours last week,

Step-by-step explanation:

The given information are;

The number of soccer players that practiced = 12 soccer players

The first quartile of the data of the recorded number of hours each soccer player practiced = 75

Therefore, given that that there are 12 soccer players, the number of data points = 12

The value of the 1st quartile is the value of the (n + 1)/4th term

When n = 12, we have;

The 12th quartile = (12 + 1)/4 = 3.25 th term with the values arranged in increasing order;

Therefore, the first quarter has the values for the first 3 players, with the lower practiced hour recorded while the recorded time for the remaining 9 players come after the first quartile;

The correct option is therefore that it must be true that exactly 3 (since we do not represent a player with the remaining fraction of 0.25 in 3.25) of the 12 soccer players practiced for at least 75 hours last week.

Answer:

Is this the complete question? is there a figure for this?

Answer:

A.

Step-by-step explanation:

Since the 2 shorter sides are greater than the longest side when added, it meet the triangle inequality thoerem. Triangle Inequality Theorom: The longest side of a triangle is less then the 2 shorter sides added.

Answer:

8,000,001 and 7,999,999

Step-by-step explanation:

200^3 = 8,000,000

(200 x 200 = 40,000

40,000 x 200 = 8,000,000)

Answer:

8 + (n-1)*9

Step-by-step explanation:

In the series, we can see that the difference between 2 consecutive terms is always 9, and the sequence starts at 8.

That means the nth term of the series must be 8 + (n-1)*9

Answer:

1.5 grams of protein.

Step-by-step explanation:

The equation that represents the relationship between protein and fat is as follows :

4p + 9f = 60 ....(1)

We need to find the grams of protein are there if there are 6 grams of fat in the snack.

Put f = 6 in the above equation (1).

4p + 9(6)= 60

4p + 54 = 60

Subtract 54 to the both sides,

4p + 54-54 = 60-54

4p = 6

⇒ p = 1.5 grams

It means the snack contains 1.5 grams of protein.

Answer:

3

Step-by-step explanation:

Given the following :

Score when there were 4 innings left = 17 to 6

Kim's team = 6 ; opposition team = 17

Opposition didn't score any point in the last 4 innings

Kim's team scored same number of points per inning and also won with the most points

Minimum Number of points Kim's team could have scored per inning :

Let number of points scored in each of the last 4 innings = p

Since they also won eventually:

Then

4p + initial points > opposition point

4p + 6 > 17

4p > 17 - 6

4p > 11

p > 11/4

p > 2.75

Hence, the minimum number of points Kim's team could have scored per inning in the last 4 would be 3( nearest whole number)

Answer:

4x+7 = 5x-20                  

(reason: vertical angles are congruent; property used: distributive)

7 = 1x-20

1x = 7+20

1x = 27

x = 27

Answer:

A.

Step-by-step explanation:

When you divide 4, it isolates the variable giving you your answer in the equation.

Answer: The answer is A, dividing both sides by 4 eliminates the variable.

Step-by-step explanation: We can find this out by following along with the steps in the process. Since we need to remove the coefficient from “x” to simplify the equation, you must divide both sides by 4 to keep both sides of the equal sign balanced. How this helped! :)

Answer:

She saved $13.56

Step-by-step explanation:

$8.64 x 7 folders = $60.48

$4.75 x 2 packs of pencils = $9.50

$6.80 x 3 packs of markers = $20.40

$60.48 + $9.50 +$20.40 = $90.38

$90.38 - 15% = $76.82 (76.823)

She saved a total of $13.56 (13.557)

Answer:

Rachel saved $13.56

Step-by-step explanation:

Pencil Packs: 2 x $4.75 = $9.50

Markers: 3 x $6.80 = $20.40

Folders: 7 x $8.64 = $60.48

Add up the costs.

$90.38

Multiply $90.38 by 0.15

13.557

Round to the nearest hundredth.

$13.58

Answer:

0.75 or three-fourth of a cup of nuts.

Step-by-step explanation:

Given that:

Original recipe has

1. One and half cups of peanut butter

2. Unknown number of cups of nuts, let this amount be [tex]x[/tex] cups.

3. Three very ripe bananas.

Total amount of chips and nuts after doubling = [tex]4\frac{1}{2}[/tex] cups

Before doubling, total amount of chips and nuts = [tex]4\frac{1}{2} \div 2 = 2.25[/tex]

Now, as per given question statement:

[tex]2.25=x+1.5[/tex]

Subtracting the number 1.5 from both the sides to find the value of [tex]x[/tex]:

[tex]2.25-1.5=x\\\Rightarrow x = \bold{0.75}[/tex]

Therefore, 0.75 or three-fourth of a cup of nuts is the original amount in the recipe.
