Answer: (-3,2)

Step-by-step explanation:

Answer:

(-3, 2)

Step-by-step explanation:

There are two methods on finding the vertex. The one I will be using is the faster version.

y=2x^{2}+12x+20

a=2   b=12   c=20

First use the formula -b/2a.

-(12)/2(2)=

=-12/4=-3

-3 is the x-coordinate.

Plug in -3 into the equation for x.

y=2(-3)^{2}+12(-3)+20

y=2(9)+12(-3)+20

y=18-36+20

y=2

The y-coordinate is 2

Use (x, y) for the vertex.

x=-3

y=2

The vertex is (-3, 2)

Hope this helps!

Answer:

Step-by-step explanation:

The point (1,1) represents 1+i in the two dimensional complex plane. Absolute value of 1+i = [tex]\sqrt{2}[/tex].

Given the complex number, z = 1+i

The general form of a complex plane is x+iy, where x and y are real numbers.

We can place any complex number into a two-dimensional complex plane with two axes - X and Y.

For z = 1+i, x = 1 and y = 1. So the point (1,1) will represent z = 1+i in the two dimensional complex plane.

The absolute value of a complex number z = x+iy is given by ,

|z| = [tex]\sqrt{x^2+y^2}[/tex]

So for z = 1+i, |z| =  [tex]\sqrt{1^2+1^2}=\sqrt{2}[/tex]

Answer:

Step-by-step explanation:

Answer:

x = 22 y = 113

Step-by-step explanation:

3x-15 = 2x+7

-2x         -2x

x-15 = 7

+15     +15

x = 22

180-51 = 129

y+16 = 129

-16       -16

y = 113

Answer:

x = 22

y = 113

Step-by-step explanation:

The angles marked as (2x+7) and (3x-15) are vertical angles, and therefore are equal to each other.

2x + 7 = 3x - 15 simplifying:

7 = x - 15

22 = x

Angles marked as (3x-15) and (y+16) form a linear pair and are therefore supplimetery. Now that we know the value of x, we can set up the following equation.

3(22) - 15 + y + 16 = 180 simplifying:

66 - 15 + y + 16 = 180

66 + y + 16 = 195

y = 113

The absolute value of the given integer(i.e. -7) is  7

Absolute value:

The absolute value (or modulus) | x | of a real number x is its non-negative value regardless of its sign.

A number's absolute value can be assumed as its distance from the origin along the real number line. Furthermore, the distance between two real numbers is the absolute value of their difference.

Let's assume the given integer=-7 and need to find the absolute value of the  given integer.

Then the absolute value of the given integer(i.e. -7) is  7

Therefore, The absolute value of the given integer(i.e. -7) is  7

Your 'b' or y-int is a little wonky, but I'm confident with what answer I'm handing to you.

The distance between the two points as depicted on the graph is:

√5.

Given, the points are:

(1,2) = (x₁,y₁) and

(3,1) = (x₂,y₂)

We know that distance between two points is:

d = √(x₂-x₁)²+(y₂-y₁)²

d = √(3-1)²+(1-2)²

d = √(2)²+(-1)²

d = √4+1

d = √5

Hence we get the distance between two given points as √5

All the given options are correct

The variation expression is given as

(2x + 3y) ∝ (x + 5y)

Rewrite as an equation

So, we have

(2x + 3y) = k(x + 5y)

Remove the brackets

So, we have

2x + 3y = kx + 5ky

Collect the like terms

So, we have

kx - 2x = 3y - 5ky

This gives

x(k - 2) = y(3 - 5k)

Divide by both sides by y(k - 2)

x/y = (5k - 3)/(2 - k) --- option (a)

Multiply both sides by y

x = y(5k - 3)/(2 - k) --- option (b)

Express x/y = (5k - 3)/(2 - k) as ratio

x : y = (5k - 3) : (2 - k) --- option (c)

The domain of the function is -2 ≤ x < -5 and the range is -2 < y < 1

The domain of the function is the set of input values of the graph

The range of a function is the set of output values of the graph.

The graph represents the given parameters

On the graph, we have the following endpoints

Closed circle at (-2, -1)

Open circle at (-5, -2)

Maximum = (0, 1)

The domain

The definition of the domain implies that the domain of a function is the set of x values of the graph.

The solution of the equation given as g = 4a +4/5 for a is a = 1/20(5g - 4)

The equation is given as

g = 4a +4/5

Multiply through the equation by 5

So, we have

5 * (g = 4a +4/5)

Evaluate the products

So, we have

5g = 20a + 4

Subtract 4 from both sides of the equation

The function rule for g(x) is (x₊6)² ₋ 5. According to the given data we apply the translations onto the graph and from the graph we determine the function of g(x).

Given, the function of f(x)  = x²

The base graph is moved up or down in the y-axis direction when a graph is vertically translated. Each point on a graph is moved k units up the graph to translate it vertically. Shifting the f (x) k units vertically will allow you to sketch the equation g (x) = f (x) + k.

The graph of g(x) is f(x) translated to 6 units left and down 5 unit.

Draw the translations onto the graph. In the given graph provided, the yellow curve indicates the function g(x).

Explicação passo-a-passo:

Podemos atribuir a incógnita x ao número de objetos que há na caixa. Assim, teremos as seguintes relações:

Metade dos objetos da caixa = 1/2x

Terça parte dos objetos da caixa = 1/3x

Portanto, o número de objetos que há na caixa será dado resolvendo a equação:

1/2x + 1/3x = 25

3/6x + 2/6x = 25

5/6x = 25
