Answer:

[tex]x = 5+\sqrt{31}\,\, and\,\, x=5-\sqrt{31}[/tex]

Step-by-step explanation:

We need to solve the quadratic equation

6 = x^2 -10x

Rearranging we get,

x^2-10x-6=0

Using quadratic formula to solve the quadratic equation

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

a= 1, b =-10 and c=6

Putting values in the quadratic formula

[tex]x=\frac{-(-10)\pm\sqrt{(-10)^2-4(1)(-6)}}{2(1)}\\x=\frac{10\pm\sqrt{100+24}}{2}\\x=\frac{10\pm\sqrt{124}}{2}\\x=\frac{10\pm\sqrt{2*2*31}}{2}\\x=\frac{10\pm\sqrt{2^2*31}}{2}\\x=\frac{10\pm2\sqrt{31}}{2}\\x = 5\pm\sqrt{31}[/tex]

So, [tex]x=5+\sqrt{31}\,\, and\,\, x=5-\sqrt{31}[/tex]

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

y > 6x + 7  

y < 6x + 9  

check one by one  

A. (3, 26)  

26 > 6(3) + 7→ 26 > 25 yes  

26 < 6(3) + 9→ 26 < 27 yes  

B. (-4, 32)  

32 > 6(-4) + 7→ 32 > -17 yes  

32 < 6(-4) + 9→ 32 < -15 no  

C. (3, 25)  

25 > 6(3) + 7→ 25 > 25 no  

25 < 6(3) + 9→ 25 < 27 yes  

DB. (4, 33)  

33 > 6(4) + 7→ 33 > 31 yes  

33 < 6(4) + 9→ 33 < 33 no  

Final answer:

Points a (3, 26) and b (-4, 32) are solutions to the system of inequalities y>6x+7 and y<6x+9. Points c (3, 25) and d (4, 33) do not satisfy both inequalities, so they are not solutions.

Explanation:

To determine which points are solutions to the given system of inequalities, y > 6x + 7 and y < 6x + 9, we need to check if they satisfy both inequalities:

Point a (3, 26): 26 > 6(3) + 7 and 26 < 6(3) + 9, which simplifies to 26 > 25 and 26 < 27. Both are true, so point a is a solution.

Point b (-4, 32): 32 > 6(-4) + 7 and 32 < 6(-4) + 9, which simplifies to 32 > -17 and 32 < -15. Both are true, so point b is also a solution.

Point c (3, 25): 25 > 6(3) + 7 and 25 < 6(3) + 9, which simplifies to 25 > 25 and 25 < 27. The first inequality is not true (it is equal, not greater), so point c is not a solution.

Point d (4, 33): 33 > 6(4) + 7 and 33 < 6(4) + 9, which simplifies to 33 > 31 and 33 < 33. Similar to point c, the second inequality is not true (it is equal, not less), so point d is not a solution.

Points a and b satisfy both inequalities and are correct solutions to the system.

Step-by-step explanation:

APEX is obnoxious, I understand.

Answer:1424.10

Step-by-step explanation:

Answer:

-2

Step-by-step explanation:

Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:

(3y)/3 = (15 - 6x)/3

y = (15 - 6x)/3

y = 5 - 2x

Note the equation:

y = mx + b

m = slope

b = y-intercept

x & y = the point (x , y)

Note that the slope is directly next to x. -2 is your answer.

~

For this case we have by definition, that the equation of a line in the slope-intersection form is given by:

[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cutoff point with the y axis

We have the following equation:

[tex]3y = 15-6x\\y = \frac {15} {3} - \frac {6x} {3}\\y = 5-2x\\y = -2x + 5[/tex]

So we have to:

[tex]m = -2[/tex]

Answer:

The slope is -2

Answer:

[tex](x-3)^{2}+(y+2)^{2}=49[/tex]

Step-by-step explanation:

The center-radius form of the equation of a circle is in the format;

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

with the center being at the point (h, k) and the radius being r units.

We simply plugin the values of the center and radius given in order to determine the equation of the circle;

The equation of the circle with center (3, -2) and radius 7 is;

[tex](x-3)^{2}+(y+2)^{2}=49[/tex]

Answer:

[tex](x-3)^2 + (y+2)^2 = 49[/tex]

Step-by-step explanation:

The general equation of a circle has the following form:

[tex](x-h)^2 + (y-k)^2 = r^2[/tex]

Where the point (h, k) represents the center of the circle and r represents the radius

In this case we know that the center is (3, -2) and the radius is 7.

Therefore:

[tex]h=3\\k = -2\\r=7[/tex]

Finally the equation of the circle is:

[tex](x-3)^2 + (y-(-2))^2 = 7^2[/tex]

[tex](x-3)^2 + (y+2)^2 = 49[/tex]

Combine like terms

3x^2-x-6

Answer:

[tex](f-g) (x) = 3x ^ 2- x - 6[/tex]

Step-by-step explanation:

We have the following functions

[tex]f (x) = 3x ^ 2-4[/tex]

[tex]g (x) = x + 2[/tex]

To find [tex](f-g) (x)[/tex] we must subtract the function f(x) with the function g (x)

Then we perform the following operation

[tex](f-g) (x) = 3x ^ 2-4- (x + 2)[/tex]

[tex](f-g) (x) = 3x ^ 2-4- x - 2[/tex]

[tex](f-g) (x) = 3x ^ 2- x - 2-4[/tex]

Finally we have that:

[tex](f-g) (x) = 3x ^ 2- x - 6[/tex]

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.)

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.

Option (B) is CORRECT.

Answer:

The shorter piece is 10 in. and the longer one is 50 in.

Step-by-step explanation:

First, let's set the shorter piece to be length x. Then the longer piece is 5x, or 5 times longer than the shorter piece.

Since both pieces combined equals to the length of the entire board, we can set these two lengths equal to it:

x + 5x = 60

And now solve for x:

6x = 60

x = 10 in (length of shorter piece)

Now let's find the length of the longer piece:

Longer = 5x = 5(10) = 50 in.

Answer:

A cone is a three dimensional solid with a circle at its cross section

Answer:

The answer is cone.

Step-by-step explanation:

A cone is a three dimensional figure, whose cross section parallel to its base, gives a circle because the base of the cone is a circle.

A cross section is defined as the slicing of a three dimensional figure to get a two dimensional figure.

Here, cone is a three dimensional figure and circle is a two dimensional figure.

So, the answer is cone.

Answer:

5 sqrt(5) =c

Step-by-step explanation:

We can use the Pythagorean theorem to find the length of the hypotenuse

a^2 + b^2 = c^2 since this is a right triangle

5^2 + 10^2 = c^2

25+100 = c^2

125 = c^2

Take the square root of each side

sqrt(125) = sqrt(c^2)

sqrt(25*5) = c

sqrt(25) sqrt(5) = c

5 sqrt(5) =c

Alright, in a right-angled triangle, the lengths of the three sides are related by the Pythagorean Theorem, which states that the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
This can be written as:
c² = a² + b²
In the question you provided, you've given that side a is 5 and side b is 10, and you'd like to find side c, the hypotenuse.
Following the Pythagorean Theorem :
c² = a² + b² = 5² + 10² = 25 + 100 = 125
Now we need to find the length of side c by taking the square root of c²:
c = √125
This can be further simplified by recognizing that 125 is equal to 25 * 5, and the square root of 25 is 5.
c = √(25 * 5) = √25 * √5 = 5√5
Therefore, the length of side c in its simplified radical form is:
c = 5√5
That would be the value of the hypotenuse of the right triangle with side lengths 5 and 10.

Answer:

(2x^2)(y^16)

Step-by-step explanation:

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:

-3/2  + (1/2)*sqrt(5)

Note: a=-3/2 , b=1/2 , c=5

Step-by-step explanation:

I think this is meant to be written as (1-sqrt(5))/(1+sqrt(5)).

First step: Multiply top and bottom by the conjugate of the bottom which is 1-sqrt(5).

When you multiply conjugates, you do have to do the whole foil thing... just do first and last  because the others will cancel.

So what I'm saying is when multiply (1+sqrt(5))(1-sqrt(5)) you will get 1-5=-4.

Second step: Multiply top out... you have to do the whole foil here because you aren't multiplying conjugates. So (1-sqrt(5))(1-sqrt(5))=1-sqrt(5)-sqrt(5)+5=

1-2sqrt(5)+5=6-2sqrt(5).

Third step:  Second step/first step =(6-2sqrt(5))/-4

Fourth step: Separate fraction 6/-4       -      2sqrt(5)/-4

Fifth step:  Simplify each fraction:  -3/2  + (1/2)*sqrt(5)

Sixth step:  If you compare the form you want it in to the form I wrote my answer in, then you should see that a=-3/2 , b=1/2 , c=5

Answer:

The range is f(x) ≥ 0

Step-by-step explanation:

The range of the function is defined as the set of values of the dependent variable for which the function is defined.

Here the function f(x) = 1/2 √x is defined for all values of x which are greater than or equal to zero or we can say all non-negative real numbers.

So, the range is  f(x) ≥ 0

Final answer:

The range of the function f(x) = ½√x is all real numbers greater than or equal to 0, which is written in interval notation as [0, ∞).

Explanation:

The range of a function is the set of all possible output values it can produce. For the function f(x) = ½√x, the domain (input values) must be non-negative because we cannot take the square root of a negative number in the real number system. Since the smallest non-negative number is 0 and the value of the function at x=0 is f(0) = ½√0 = 0, the function starts at 0. The square root function increases as its input increases; thus, for any positive value of x, you get a positive value for f(x). Moreover, as x approaches infinity, the output of the function also grows without any upper bound, although it does so slower than the increase in x.

Therefore, the range of the function f(x) = ½√x is all real numbers greater than or equal to 0, which can be written in interval notation as [0, ∞).

Answer:

B

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
