Answer:

Function.

Step-by-step explanation:

A relation is a function every x that in your domain only gets assigned to exactly one number in your range.

Basically if you have a set of points and you see that the same x is being used more than once, then it isn't a function (unless for some reason they repeated the same point).

So the x's I see in the order that your points are is 3,1,-1,-2.  All of these x's are different so it is a function.

Answer: Yes, it is a function.

Step-by-step explanation:

Usually we denote the input value as 'x' and the output value as 'y'.

The given relation: {(3, −5), (1, 2), (−1, −4), (−2, 2)}

Here , each input value corresponds an unique output value.

Therefore , the given relation is a function.

[tex]\angle 12 \cong \angle 8\\\angle 4 \cong \angle 8[/tex]

Step-by-step explanation:

When two parallels lines are crossed by a transversal, certain pair of angles are called corresponding angles, specifically, those that are placed in the same side of the transversal, on inside the parallels and the other outside the parallels. The image attached shows an example of corresponding angles.

So, we observe in the given image that all corresponding angles with angle 8 are

[tex]\angle 12\\\angle 4[/tex]

These angles are form corresponding angle with [tex]\angle 8[/tex], that means they are congruent, that is

[tex]\angle 12 \cong \angle 8\\\angle 4 \cong \angle 8[/tex]

Answer:

[tex]Z=2.99999999999995[/tex]

Step-by-step explanation:

We can write the proportionality equation as:

[tex]Z=k\frac{X}{Y}[/tex]

Note: Directly proportional goes top and top, multiplied. And inversely proportional goes top bottom, divided. Also, k is the proportionality constant.

When X is 3, Y is 19, Z is 0.94736842105263. Plugging these, we figure out k:

[tex]Z=\frac{kX}{Y}\\0.94736842105263=\frac{k(3)}{19}\\k=\frac{0.94736842105263*19}{3}\\k=5.99999999999999[/tex]

Now we put X = 13 and Y = 26 and k = 5.99999999999999, to find Z:

[tex]Z=\frac{kX}{Y}\\Z=\frac{(5.99999999999999)(13)}{26}\\Z=2.99999999999995[/tex]

The correct answer is: True

Step-by-step explanation:

First do what is replacing the variables by changing X to 2 and Y to -3

3(2)^2 + 4(-3)^2 = 3(4) + 4(9) = 12 + 36 = 48

Answer: The value is 48

Step-by-step explanation:

Given the following expression:

[tex]3x^2+4y^2[/tex]

You need to substitute the values of each variables provided in the exercise into this expression. You can observe that the value of the variable "x" and  the value of the variable "y" are:

[tex]x=2 \\ y=-3[/tex]

Therefore, substituting values, you get:

[tex]3x^2+4y^2=3(2)^2+4(-3)^2=3(4)+4(9)=12+36=48[/tex]

The answer is A.

Because both angles of triangles are equal to 42° that means the distance of UV is equal to the distance of XY.

Answer:

The new function is (x + 7)² - 47 ⇒ the 3rd answer

Step-by-step explanation:

* Lets put the function f(x) in the vertex form at first and then make

 the translation

∵ The general form of the quadratic function is

  f(x) = ax² + bx + c

∵ The x-coordinate of the vertex of the function is -b/2a

∵ The y-coordinate of the vertex of the function is f(-b/2a)

- Lets find a , b from the function two find the vertex point

∵ f(x) = x² + 22x + 58

∴ a = 1 , b = 22 , c = 58

∵ x-coordinate of the vertex = -b/2a

∴ x-coordinate of the vertex = -22/2(1) = -11

∵ y-coordinate of the vertex = f(-11)

∴ f(-11) = (-11)² + 22(-11) + 58 = 121 - 242 + 58 = -63

∴ The vertex point is (-11 , -63)

- The vertex form of the quadratic function is f(x) = (x - h)² + k , where

  (h , k) are the coordinates of the vertex point

∵ The vertex point is (-11 , -63)

∴ h = -11 , k = -63

∴ f(x) = (x - -11)² + -63

∴ f(x) = (x + 11)² - 63

* lets revise the rules of the translation

- If the function f(x) translated horizontally to the right  

 by m units, then the new function g(x) = f(x - m)

- If the function f(x) translated horizontally to the left  

 by m units, then the new function g(x) = f(x + m)

- If the function f(x) translated vertically up  

 by n units, then the new function g(x) = f(x) + n

- If the function f(x) translated vertically down  

 by n units, then the new function g(x) = f(x) – n

∵ f(x) will translate 4 units to the right

∴ m = 4

∵ f(x) ⇒ f(x - m)

∴ (x + 11)²  ⇒ (x + 11 - 4)² = (x + 7)²

∵f(x) will translate 16 units up

∴ -63 will add by 16

∴ n = 16

∴ f(x) ⇒ f(x) + n

∵ -63 + 16 = -47

∴ The new function is (x + 7)² - 47

(x + 7)^2 - 47

Answer:

10x

Step-by-step explanation:

The greatest common factor of the polynomial 30x³ - 20x is 10x.

Option B is the correct answer.

We have,

To find the greatest common factor (GCF) of the polynomial

30x³ - 20x, we need to determine the largest expression that can be factored out from both terms.

Let's look at the coefficients first.

The coefficients of the terms are 30 and -20.

Both numbers are divisible by 10, so we can factor out 10.

Now let's consider the variable, x. In the first term, we have x³, and in the second term, we have x.

The lowest power of x that appears in both terms is x, so we can factor out x.

Putting it together, we can factor out the GCF of 10x:

GCF(30x³ - 20x) = 10x

Therefore,

The greatest common factor of the polynomial 30x³ - 20x is 10x.

Given:

triangle XYZ  is rotated by a composition of 50°+40°=90° both about point y

Now when a geometrical figure is rotated by any degree then its shape or size does not change and remain same.

As the triangle is rotated clockwise by 90  degrees about point y then diagram attached is formed .

option a is correct.

Answer:

The correct option is A.

Step-by-step explanation:

If the direct of rotation is not mentioned, then it is consider as counterclockwise rotation.

It is given that triangle XYZ rotated 50 degrees and a 40 degrees, both about point Y.

It means the figure triangle XYZ rotated 90 degrees counterclockwise  about the point Y.

In option A, triangle XYZ rotated 90 degrees counterclockwise  about the point Y.

In option B, triangle XYZ rotated 180 degrees counterclockwise about the point Y.

In option C, triangle XYZ rotated 270 degrees counterclockwise  about the point Y.

In option D, triangle XYZ rotated 360 degrees counterclockwise  about the point Y.

Therefore the correct option is A.

Answer:

540

Step-by-step explanation:

f(x) = x(x - 1)

g(x) = 3x

(f* g)(x) = x(x - 1) 3x

            = (x^2 -x) * 3x

            = 3x^3 -3x^2

            =3x^2(x-1)

Let x = 6

(f* g)(6) = 3*6^2( 6-1)

            =   3*36 *5

                   540        

Answer:

540

Step-by-step explanation:

(f*g)(6)=f(6)*g(6).

Now we need to find f(6) and g(6).  Once we find their values we multiply them.

f(6) means to replace x in x(x-1) with 6:

6(6-1)

6(5)

30

So f(6)=30.

g(6) means to replace x in 3x with 6:

3(6)

18

So g(6)=18.

(f*g)(6)=f(6)*g(6)=30*18=540.

Answer : The value of 'x' is, 8

Step-by-step explanation :

According to the theorem, if two chords intersect inside a circle then the product of the lengths of the one chord equals to the length of another chord.

That means in the given figure,

AO × OB = CO × OD

Given:

Length AO = 10

Length OB = 4

Length CO = x

Length OD = 5

Now put all the given values in the above expression, we get:

AO × OB = CO × OD

10 × 4 = x × 5

40 = x × 5

x = 8

Therefore, the value of 'x' is, 8

Answer:

Step-by-step explanation:

I'm going to look at y=3x+2 first.

This is a linear equation in slope-intercept form.

Slope-intercept form is y=mx+b.

It is called slope-intercept form because it tells us m, the slope, and b ,the y-intercept.

So I'm going to draw a point at 2 on the y-axis (because 2 is our y-intercept).

From that point, I'm going to count up 3 and right once because our slope is 3 (which is 3/1; slope=rise/run).  So my next point will be at (1,5).

Now let's go back to y>3x+2.

Since it says y>, then we shade above.

If it had said y<, then we shade below.
