A.) x-2/x+4
B.) 3x-8/x
C.) x-14/x+4
D.) 3x-4/x

Answer:

B

Step-by-step explanation:

So, for this problem, it is only asking for vertex A, so you only have to apply the transformations to one point (unless you want to find out where the other points are at).

Vertex A is at (-4,2).

The triangle is first translated 2 units right and 5 units down.

So to find the coordinate of that you have to understand that is you translate something right or left, the x value will change. And if it's up or down, the y value will change. If you are going right or up, the amount it's moved will be added. And left or down will be subtracted.

-4+2=-2 (so the new x-value will be -2)

2-5=-3 (so the new y-value will be -3)

Thus vertex A' is (-2,-3).

Now for the next transformation.

(-2,-3) is moved 5 units right and 4 units up.

-2+5=3 (so x-value will be 3)

-3+4=1 (so the y-value will be 1)

SO, the new coordinate of vertex A" is...

(3,1)! aka B

(Also, you can just illustrate this on a graph but i'm showing it to you this way because when you get more advanced the amount it is being translated will be much higher.)

Answer:

748 in^3.

Step-by-step explanation:

This consists of a triangular prism and a  rectangular cuboid .

Volume of the prism =  .1/2 * 8 *11 * 17 = 748 in^3

Volume of the cuboid =  5*8*17 = 680 in^3

Therefore the volume of the whole figure

= 680 + 748 =  1428 in^3.

In order to change from 35 to 62, we have to add 27. So, the question becomes: which percentage of 35 is 27?

To answer this question, we set this simple equation

[tex]27 = 35\cdot\dfrac{x}{100}[/tex]

And solving for x we have

[tex]x = \dfrac{2700}{35} \approx 77.14[/tex]

So, if you change from 35 to 62, you have an increase of about 77%

The percentage change is 77.14%

The following information can be gotten from the question:

Old number = 35

New number = 62

Increase in number = 62 - 35 = 27

Percentage change will be:

= (Increase in number / Old number) × 100

= 27/35 × 100

= 2700/35

= 77.14%

In conclusion, the percentage change is 77.14%

Answer:

Step-by-step explanation:

Given

3x - y = 2

Substitute y = x - 1 into the equation

3x - (x - 1) = 2

3x - x + 1 = 2 ← simplify left side

2x + 1 = 2 ← required equation after substitution

Given.

3x - y = 2

Substitute x - 1 for variable y.

3x - x - 1 = 2 ← Resulting equation

To find the inverse of an equation just switch the places of the x and y, then solve for y like so...

(keep in mind that f(x) means the same thing as y)

original equation:

y = 4x + 8

switching x and y:

x = 4y + 8

x - 8 = 4y

The factors are - 7 and - 8, since

- 7 × - 8 = + 56 and - 7 - 8 = - 15, hence

x² - 15x + 56 = (x - 7)(x - 8)

Answer:

The solutions are:

x1= 5 +√31

x2= 5 -√31

Step-by-step explanation:

We have 6=x^2-10x

Balance the equation by adding the same constant to each side

x^2-10x+25=6+25

x^2-10x+25=31

Rewrite as perfect square,

(x-25)^2=31

Taking square root at both sides

√(x-5)^2 = √31

x-5 = (+/-)√31

x1= 5 +√31

x2= 5 -√31

Therefore the solutions are x1= 5 +√31 , x2= 5 -√31

When point D in shape ABCDE is reflected over the x-axis, the y-coordinate changes its sign. If it is then translated 3 units to the left, the x-coordinate of D decreases by 3. Therefore, if the original coordinates of D are (d1, d2), after these transformations, its new coordinates will be (d1-3, -d2).

To answer this question, we need to understand how the reflection and translation transformations affect the coordinates of point D in the shape ABCDE.

First, when a point is reflected over the x-axis, the y-coordinate changes sign. For example, if the original coordinates of D are (d1, d2), after reflection over the x-axis, the new coordinates will be (d1, -d2).

Next, a translation of 3 units to the left (in the negative x direction), lowers the x coordinate by 3 units. Thus, after this translation, the final coordinates of point D will be (d1-3, -d2).

So, if you know the original coordinates of point D in the shape ABCDE, you can calculate its new position after these transformations in the described way.

Answer:  The correct option is (B) 7.

Step-by-step explanation:  Given that a karate studio charges $35 for the first course and $22.50 for each course after that, even if the student leaves the course early.

Cena paid $170 for her son to take courses.

We are to find the number of courses that he took.

Let x represents the number of courses that Cena took.

Then, according to the given information, we have

[tex]35+22.50\times (x-1)=170\\\\ \Rightarrow 22.50(x-1)=170-35\\\\ \Rightarrow 22.50(x-1)=135\\\\ \Rightarrow x-1=\dfrac{135}{22.50}\\\\\Rightarrow x-1=6\\\\ \Rightarrow x=7[/tex]

Thus, the required number of courses that Cena took is 7.

Follow below steps;

To solve for the dimensions of the picture whose length is 22.75 inches shorter than twice the width and has a perimeter of 116.5 inches, we first need to set up equations based on the given information.

Step 1: Set up the equations

Let w represent the width of the picture. Then, the length will be 2w - 22.75 inches.

Since the perimeter of a rectangle is given by the formula P = 2l + 2w where l is the length and w is the width, we can substitute the expressions for length and width to get the perimeter equation:

116.5 = 2(2w - 22.75) + 2w

Step 2: Solve for width

Expanding the perimeter equation we get:

116.5 = 4w - 45.5 + 2w

Combining like terms:

116.5 = 6w - 45.5

Adding 45.5 to both sides:

116.5 + 45.5 = 6w

162 = 6w

Divide both sides by 6 to find w:

w = 162 / 6

w = 27 inches

Step 3: Find the length

Now we calculate the length using the width (w = 27):

Length = 2w - 22.75

Length = 2(27) - 22.75

Length = 54 - 22.75

Length = 31.25 inches

So, the dimensions of the picture are a width of 27 inches and a length of 31.25 inches.

Answer:

When Harold wrote his equation, the point he used was (7, 0) ⇒ the third answer

Step-by-step explanation:

* Lets look to the equation to find the correct answer

- He used the point-slope form is y – y1 = m(x – x1), where m is the

 slope of the line , (x1 , y1) are the coordinates of the point which

 the line passes through it and (x , y) are the coordinates of any

 general point on the line

- Lets solve the problem

- Harold correctly wrote the equation y = 3(x – 7)

∵ y - y1 = m (x - x1)

∵ y = 3 (x - 7)

- By comparing between the two equations

∴ y1 = 0

∴ m = 3

∴ x1 = 7

- He used the point (x1 , y1)

∴ Harold used the point (7 , 0) to write the equation

∴ The answer is when Harold wrote his equation, the point he used

   was (7, 0)

ANSWER

When Harold wrote his equation, the point he used was (7, 0).

EXPLANATION

The point-slope form is given as

[tex]y-y_1=m(x-x_1)[/tex]

The equation Harold wrote correctly is:

[tex]y = 3(x - 7)[/tex]

This is the same as:

[tex]y - 0= 3(x - 7)[/tex]

Comparing to point-slope form, we have

[tex]x_1=7 \: \: and \: \: y_1=0[/tex]

Hence the point is (7,0)

When Harold wrote his equation, the point he used was (7, 0).

Answer:

Step-by-step explanation:

4x + 2y = 3

(send 2y to the right and 3 to the left)

4x - 3 = -2y

(divide everything by -2)

(4x)/(-2) - 3/(-2) = y

So now we have a function which is like

y = ax + c

c = the y value of intersection point of the equation and the y-axis

a = amount of increase in y values per x value

so in this example:

(4x/(-2)) = (4/(-2))x -> a = 4/(-2) = -2

and

c = -3/-2 = 3/2

So the graph that we're searching for is increasing (-2) y values (so decreasing 2 y values) per 1 x value and has an intersection with the y-axis where y = 3/2
