What is the length of side x?

Answer

This part is already solved in the question:

The graph is shown at the bottom

The given equation is:

6 - 2x = 3

-2x = 3-6

-2x = -3

2x = 3

x = 3/2

x = 1.5

This can also be solve by seeing the graph. The equation which was given to us was y = 6 - 2x, and in this part we have to find the value of 3 = 6 -2x , which means y=3.

We can see in the graph that y = 4 when x = 1 and y = 2 when x = 2, so as y=3 is the midpoint of 4 and 2, the values corresponding to y = 3 should be midpoint of 1 and 2 i.e 1.5

Answer:

-64

Step-by-step explanation:

When given two points we can use the slope formula

m = (y2-y1)/(x2-x1)

   = (-7 -57)/(38-37)

    =-64/1

  = -64

Answer:

The experimental probability is 0.8% more than the theretical probability,

There were approximately 2 more winners than expected

Step-by-step explanation:

Theoretical Probability is given by = 1/8 = 12.5%

Which means that out of 324 players, numbers of winners theoretically are = 0.125 · 324 = 40.5 ≅ 41

To find the probability of experimental data, we have to consider the data recorded by Talia and Yoshi

Recorded winners = 43

Total players = 324

Experimental Probability =  Numbers of winners/ Total Number of players · 100

Experimental Probability = 43/321 · 100 = 13.3%

The difference between Experimental and Theoretical Probability is = 13.3% - 12.5% = 0.8%

Difference of Winners ≅ 43 - 40.5 ≅ 2

Answer:

72

Step-by-step explanation:

Step 1: Figure out percentages of what he owns

360(0.4) = 144 models he made

360 - 144 = 216 models he bought.=

Step 2: Figure out percentages of what he donated

144(0.25) = 36 models he donated (he made)

216(0.5) = 108 models he donated (he bought)

Step 3: Find the difference

108 - 36 = 72

And we have our answer!

Answer:

The inverse is 1/4x + 9/4

Step-by-step explanation:

f(x) = 4x − 9

y = 4x -9

Exchange x and y

x = 4y -9

Solve for y

Add x to each side

x+9 = 4y

Divide by 4

1/4x + 9/4 = y

The inverse is 1/4x + 9/4

Answer:

The standard method for solving an equation like 3x + 5 = 26 is to use the Subtraction Property of Equality and then the Division Property of Equality.

Step-by-step explanation:

To solve, you subtract both sides by 5 first. Then you divide both sides by 3 to isolate the x.

Answer:

y= 2/3x + 2

Step-by-step explanation:

Answer:

y = 2/3x − 2.

Step-by-step explanation:

We essentially just want a  y  on the left side, so let's subtract 2x from both sides to get  −3y = −2x + 6.

Lastly, let's divide both sides by −3 to get y = 2/3x − 2.

Our equation is now in slope-intercept form, where the slope is 2/3 and our y-intercept is −2.

Answer:

[tex]W(x)=30x+70[/tex]

Step-by-step explanation:

First, we will find the weight of the table. We know that 8 boxes weighs a total of 240 kg since each box weights 30 kg. Then to find the weight of the table, we can subtract the total weight from the weight of the boxes. Thus:

[tex]W_{\text{table}}=310-240=70\text{ kg}[/tex]

So, the weight of the table is 70 kg.

Now, we can write our function. Let [tex]x[/tex] equal the amount of boxes.

The table is a set weight, so that would be our constant.

Thus, we will have:

[tex]W(x)=30x+70[/tex]

Where W(x) represents the weight of the table after adding x boxes.

30x represents the weight each box of book adds to the total. One box equals 30 kg, two boxes equal 60 kg, etc.

The 70 represents the unchanging weight of the table.

Answer:

Step-by-step explanation:

Well first, we need to find the weight of the table. We know that 8 boxes weighs a total of 240kg (since each box weights 30kg). Thus, we can conclude that the table weighs 70kg by doing 310-240=70.Now, we can write our function. Let  equal the amount of boxes.

The table is a set weight, so that would be our constant so, we will have: 30x represents the weight each box of book adds to the total. One box equals 30kg, 2 boxes equal 60kg, etc.The 70 represents the unchanging weight of the table.In terms of W(x), it will be:

Answer:

(-15,12),(6,18)(12,-9)

Step-by-step explanation:

Given

A (-5, -4), B (2, 6), and C (4, -3)

Dilated from (x,y) to (3x,3y)

Required

Vertices of the dilated image

First, the scale factor has to be calculated

This is calculated as thus;

Dilation = Original * Scale Factor;

In case of (x,y) to (3x,3y)

So, we have

[tex](3x,3y) = Scale\ Factor * (x,y)[/tex]

Simplify brackets

[tex]3(x,y) = Scale\ Factor * (x,y)[/tex]

Divide both sides by (x,y)

[tex]\frac{3(x,y)}{(x,y)} = \frac{Scale\ Factor * (x,y)}{(x,y)}[/tex]

[tex]\frac{Scale\ Factor * (x,y)}{(x,y)}=\frac{3(x,y)}{(x,y)}[/tex]

[tex]Scale\ Factor =\frac{3(x,y)}{(x,y)}[/tex]

[tex]Scale\ Factor =3[/tex]

Now, the vertices of the new image can be calculated;

Using the formula: Dilation = Original * Scale Factor;

At vertex A(-5,4)

Dilation = (-5,4) * 3

Dilation = (-5*3 ,4*3)

Dilation = (-15,12)

At vertex B(2,6)

Dilation = (2,6) * 3

Dilation = (2*3 ,6*3)

Dilation = (6,18)

At vertex C(4,-3)

Dilation = (4,-3) * 3

Dilation = (4*3 ,-3*3)

Dilation = (12,-9)

Hence, the vertices of the dilated image are (-15,12),(6,18)(12,-9)

Answer: B

Step-by-step explanation:

This looks like a cosine function. Cosine can take on any x value and still be defined. That means all real numbers will work. When asked for domain, it really just means what x values are defined for this function. We just said, cosine can take any x value

If you didnt know this was a cosine function, you could just visually see the function goes on to -∞ and +∞. There's no reason for the function to run into a critical point

The given transformed function is

                      [tex]y = \sqrt[3]{\frac{1}{2}x }[/tex]

Explanation:-

Given function  y = ∛x

A horizontal stretch by a factor of 1/k

                                               [tex]y = f(\frac{x}{k} )[/tex]

The given transformed function is

                      [tex]y = \sqrt[3]{\frac{1}{2}x }[/tex]

Final answer:-

It is horizontally stretched by a factor of 1/2

The given transformed function is

                      [tex]y = \sqrt[3]{\frac{1}{2}x }[/tex]

Answer:

x-intercept → (-4, 0)

y-intercept → (0, -2.44)

Domain: (-∞, ∞)

Range: (-∞, ∞)

Step-by-step explanation:

Given function is f(x) = [tex]-\sqrt[3]{(x+3)}-1[/tex]

For x-intercept,

[tex]-\sqrt[3]{(x+3)}-1=0[/tex]

[tex]-\sqrt[3]{(x+3)}=1[/tex]

[tex]\sqrt[3]{(x+3)}=-1[/tex]

(x + 3) = -1

x = -4

Therefore, x-intercept → (-4, 0)

For y-intercept,

Substitute x = 0 in the function.

f(x) = [tex]-\sqrt[3]{(0+3)}-1[/tex]

     = [tex]-\sqrt[3]{3}-1[/tex]

     = -1.44 - 1

     = -2.44

Therefore, y-intercept → (0, -2.44)

Domain: This function is defined for all real values of x.

Therefore, Domain: (-∞, ∞)

Range: Since this function is defined for all real values of x, we will get a distinct output value for every distinct input values.

Therefore, Range: (-∞, ∞)
