Click on the correct answer.

10x² +7
10x + 7
7x + 10

The answer is B

When there is a solid point that means it is included in the graph, so you'd use a greater/less than or equal to symbol (the one with a line under). If it's an unfilled point then it means that it is not included in the graph, so you'd use a greater/less than sign.

The x² equation is less than 2 while the linear equation is greater than or equal to 2.

We know it's the x² equation that is less than two because it has a curve in it.

Answer:

2(5x-2)(5x+2)

Step-by-step explanation:

Answer: Writing an equation in function form. You want to remove the x term from the side y is on and move it to the other side of the equal sign. To do this either add or subtract the x term from both sides. Next divide by the coefficient of the y term. Now your equation is in function form.

Answer:

A and C

Step-by-step explanation:

solving the equations

A

x² - 4 = 0 ( add 4 to both sides )

x² = 4 ( take square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2 ← required solution

B

x² = - 4 ← has no real solutions

C

4x² = 16 ( divide both sides by 4 )

x² = 4 ( take square root of both sides )

x = ± [tex]\sqrt{4}[/tex] = ± 2 ← required solution

D

2(x - 2)² = 0 , then

x- 2 = 0 ( add 2 to both sides )

x = 2 ← not the required solution

Answer:

Answer A and C

Step-by-step explanation:

Let us solve the equations one by one and let us check whether the answers are matching with the answers given in the questions.

A) x² - 4 = 0

   ( x² - 2² ) = 0

   ( x -2 ) ( x + 2 ) = 0

   ∴ x - 2 = 0                   or           x + 2 = 0

      x = 2                                       x = -2               ( Matched )

B) x² = -4

  x = ±√-4  ← no real solutions                    (Not matched )

B)   3x² + 12 = 0

      3 ( x² + 4 ) = 0

      3 ( x² + 2² ) = 0 ← no real solutions      (Not matched)

C) 4x² = 16

Divide both sides by 4.

 x² = 4

 x = ±√4

 ∴ x = 2         or        x = -2       (Matched)

 D) 2 ( x - 2 )² = 0    

      (2x - 4)² = 0

      4x² - 16x + 16 = 0

Divide the whole equation by 4.

   x² - 4x + 4 = 0

 x² - 2x - 2x + 4 = 0

x ( x - 2 ) - 2 ( x - 2 ) = 0

( x - 2 ) ( x - 2) =

∴ x - 2 = 0          or        x - 2 = 0

  x = 2                            x = 2                 ( Not matched )

The area of a 2D form is the amount of space within its perimeter. The surface area of the prism is 232 in².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The surface area of the prism is,

Surface area = 2 [(2 × 8)+(8 × 10)+(2 × 10)]

Answer:

[tex]x=1[/tex] ± [tex]i\sqrt{19}[/tex]

Step-by-step explanation:

First off let's state the quadratic formula

Quadratic formula

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

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

For this question our quadratic equation is

[tex]x^2+20=2x[/tex]

Now before we can apply the quadratic formula we first have to set the equation equal to zero. We do this my moving everything to one side and setting it equal to zero.

In this case, we simply move the 2x to the other side making it negative and setting the equation equal to zero.

[tex]x^2-2x+20=0[/tex]

From here we plug in the values to the quadratic equation.

Now incase you don't know

[tex]a =[/tex] Coefficient of [tex]x^2[/tex] value

[tex]b=[/tex] Coefficient of [tex]x[/tex] value

[tex]c=[/tex] The Constant

Now plug in values

[tex]a=1[/tex]

[tex]b=-2[/tex]

[tex]c=20[/tex]

To get the values of x using the quadratic formula we have the plug in the values, we also have to both subtract and add the [tex]\sqrt{b^2-4ac}[/tex] to [tex]-b[/tex]

Plug in values into formula

[tex]\frac{2+\sqrt{(-2)^2-4(1)(20)} }{2(1)}[/tex]

[tex]\frac{2+\sqrt{-76} }{2}[/tex]

[tex]\frac{2+\sqrt{-1} *\sqrt{76} }{2}[/tex]

[tex]\frac{2+i *\sqrt{76} }{2}[/tex]

[tex]\frac{2+i *\sqrt{4(19)} }{2}[/tex]

[tex]\frac{2+i *\sqrt{2^2(19)} }{2}[/tex]

[tex]\frac{2+2i \sqrt{19} }{2}[/tex]

[tex]x=1+i\sqrt{19}[/tex]

Now repeat the steps except subtract from -b rather than add to it.

Polygon is given as a closed two-dimensional figure with three or more straight lines.

The given vertices of polygon ABCDE are A(2, 8), B(4, 12), C(10, 12), D(8, 8) and E(6, 6)

After reflection new polygon formed MNOPQ has the vertices M(-2, 8), N(-4, 12), O(-10, 12), P(-8, 8) and Q(-6, 6).

By comparing the vertices we find the x-coordinates of polygon ABCDE have been changed to MNOPQ by negative notation only. Y- coordinates are same.

Therefore, polygon ABCDE has been reflected across the y-axis.

Option C. is the answer.

If polygon MNOPQ is translated 3 units right and 5 units down then the new vertices of congruent polygon VWXYZ will be

M(-2, 8) = [(-2 - 3), (8 + 5)] = (-5, 13)

N(-4, 12) = [(-4 - 3), (12 + 5)] = (-7, 17)

O(-10, 12) = [(-10 - 3),(12 + 5)] = (-13, 17)

P(-8, 8) = [(-8 - 3), (8 + 5)] = (-11, 13)

Q(-6, 6) = [(-6 -3),(6 + 5)] = (-9, 11)

Thus, Option A. is the correct option.

Based on the data, it is found that "being female" and "earning over $50,000" are not independent events. the correct answer is option D.

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Two events, A and B are independent, if:

P(A [tex]\cap[/tex] B) = P(A) P(B)

In this problem, the events are:

Out of the 1000 people, 450 are female, hence:

P(A) = [tex]\dfrac{450}{1000}[/tex] = 0.45

850 earn over $50,000, hence:

P(B) = [tex]\dfrac{850}{1000}[/tex] = 0.85

375 are women who earn over $50,000, hence:

P(A [tex]\cap[/tex] B)  = [tex]\dfrac{375}{1000}[/tex] = 0.375

The multiplication of the probabilities is:

P(A [tex]\cap[/tex] B)  = 0.45(0.85} = 0.3825

Therefore based on the data, it is found that "being female" and "earning over $50,000" are not independent events. the correct answer is option D.

Checking the sign of k :

If the graph is translated up then k > 0

If the graph is translated down then k < 0

Answer:

(-2, -4)

Step-by-step explanation:

You can complete the square of the equation to get

y+(4/2)^2 = x^2+4x+(4/2)^2

y+4 = x^2 + 4x + 4

y+4 = (x+2)^2

y = (x+2)^2 - 4

This gives the form y = a(x-h)^2 + k where (h, k) is the vertex of the equation. You can also arrive at the same conclusion by making some observations of the equation. (x+2)^2 minimum value is going to be 0 since and negative values resulting from x+2 is going to become positive because of the square. So the minimum value is when x+2 is 0 or when x is equal to -2 and when it's at that minimum value of 0 it's going to have 4 subtracted from it which gives the vertex of (-2, -4)
