Find the value of x
A.)25
B.)140
C.)5
D.)1

Answer:

6

Step 1: Solve Square Root

Vx+3=x-3

x+3=(x-3)^2 (squared both sides)

x+3=x^2-6x+9

x+3-(x^2-6x+9)=0

(-x+1)(x-6)=0 (factor left side of equation)

-x+1=0 or x-6=0

x=1 or x=6

When you plug it in to check

1 (Doesn't Work)

6 (Work)

Therefore, 6 is your solution.

Answer:

x=2

Step-by-step explanation:

Since the angles are equal, the side lengths are equal  (isosceles triangle)

12 =6x

Divide by 6

12/6 = 6x/6

2= x

Answer:

a≈13.27

Step-by-step explanation:

Context for variables

a= Side legth

A=Area

Answer:

A = 20.25 sq units

Step-by-step explanation:

to find the area of a square you only need to know the measure of one side -- all other sides will be equal to it

it appears the segment is 4.5 units so you would square that to get the area

A = 4.5²

A = 20.25

Answer:

a =1  and b =2

Step-by-step explanation:

The standard quadratic is written in the form

ax^2 +bx+c =0

x^2 +2x -13 =0

a =1  and b =2

Answer:

57 + x = 360

-57         -57

X = 303 degrees

Step-by-step explanation:

Full circle equals 360 degrees

Given degree is 57

Unknow value will be replaced as x

Unknown value(x) and given degree added together willl equal 360 degrees in total:

57 + x = 360

Answer:

Given b=1.7 and ∠β=39°,

So

x = 2.70133

Answer:

103

Step-by-step explanation:

Find the area of the rectangle on the top

A = 7*13 = 91

Now find the area of the rectangle on the bottom

13 - (5+5) = 3

11-7 = 4

The dimensions of the bottom rectangle are 3 by 4

A = 3*4 = 12

The total area is 91+12 = 103

Answer:

A = 68

B = 44

Step-by-step explanation:

The sum of the angles of a triangle add to 180

A+B+C =180

x + x-24 +68 = 180

Combine like terms

2x+44 =180

Subtract 44 from each side

2x+44-44= 180-44

2x = 136

Divide by 2

2x/2 = 136/2

x = 68

A = x = 68

B = x-24 =44

Answer: I’m confused with A but I’m 100% sure B is 44 I hope this helped

Answer:

( [tex]\frac{1}{2}[/tex], 0 )

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

2x² + 3x - 2 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × - 2 = - 4 and sum = + 3

The factors are + 4 and - 1

Use these factors to split the x- term

2x² + 4x - x - 2 = 0 ( factor the first/second and third/fourth terms )

2x(x + 2) - 1 (x + 2) ← factor out (x + 2) from each term

(x + 2)(2x - 1) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

The x- intercepts are (- 2, 0 ), ( [tex]\frac{1}{2}[/tex], 0 )

Hi there!

[tex]\large\boxed{k> 6.125}[/tex]

We can use discriminants to determine the value of k for which the equation would have complex solutions. (Those involving i)

If b² - 4ac < 0, then the equation will have complex solutions. Therefore:

Plug in the given values of b and a to solve:

7² - 4(2)(k) < 0

Simplify:

49 - 8k < 0

Solve the inequality:

49 < 8k

6.125 < k

k > 6.125. Anything greater than 6.125 would result in complex solutions.

Answer:

Simplified version: [tex]9\sqrt{7}[/tex]

Step-by-step explanation:

[tex]\sqrt{567}[/tex]

[tex]\sqrt{81} *\sqrt{7} = \sqrt{567}[/tex]

We know that √81 is a perfect square, therefore √81 = 9,

[tex]9\sqrt{7} = \sqrt{576}[/tex]

Hope this helps!

Answer:

A' = (0,0)

B' = (6,-12)

C' = (-12,-12)

Step-by-step explanation:

According to the Question,

A = (0,0)  , B = (2,-4)  , C = (-4,-4)

A = (0,0) becomes A' = (0,0). No change happens. This point is fixed

B = (2,-4) becomes B' = (6,-12). This point does move

C = (-4,-4) becomes C' = (-12,-12). This moves as well

So all you need to do from here is draw triangle A'B'C'.

Answer:

x = 3 11/45

Step-by-step explanation:

x = 3.244444444

Multiply by 10

10x = 32.44444444

Subtract the first equation from the second equation

10x = 32.44444444

-x =      3.244444444

---------------------------

9x = 29.2

Divide each side by 9

9x/9 = 29.2 /9

Multiply top and bottom by 10

x =292/90

x =146/45

x = 3 11/45

Answer:

Part A

5 m

Part B

The maximum displacement of the Ferris wheel from the midline

Step-by-step explanation:

Part A

The amplitude is the largest displacement of a body, moving in an oscillatory, or vibrational motion from its position of equilibrium or central position about which the body vibrates

In the Ferris wheel, the central position is the midline, between the maximum height and the minimum height

Therefore, the amplitude is the maximum displacement from the midline = The maximum height - ((The maximum height - The minimum height)/2 + The minimum height)

∴ The amplitude = 11 m - ((11 m - 1 m)/2) + 1 m) = 5 m

Part B

The amplitude represents the maximum and minimum distances the Ferris wheel moves above the midline.

To determine the amount Jimmy made last week, you will need to calculate the commission he made on his sales and add the $500 to that amount.

Here is the math equation showing this:

($1540 x 0.08) + $500 = $623.20

Jimmy made $623.20 last week.

Answer:

Y(4) = 200(1.1)^4

Step-by-step explanation:

Given that :

Number of tickets purchased before consecutive wins = 200

For each consecutive win, ticket purchased increases by a factor of 1.1

Number of tickets after 4 wins

This scenario describes an exponential relation :

Where increase is factor based and not a certain number :

Hence,

Number of tickets, Y= Initial number of ticket * growth factor^number of wins

Hence, we have

Y(n) = 200(1.1)^n

Y(4) = 200(1.1)^4 = 292.82

Step-by-step explanation:

the answer is 1 because every time the number doubles
