Answer:

12x-6>7x=19

Step-by-step explanation:

Answer:

It's proved below

Step-by-step explanation:

We are given;

- K is the midpoint of JL

- M is the midpoint of LN

By definition of mid points, we can say that;

JK = KL and LM = MN

Now, we are given that JK = MN.

Thus, by substitution, we can deduce that; KL = LM

Thus is because JK can be replaced with KL and MN can be replaced with LM.

Thus, it is proved that KL = LM

Answer:

B 12.54

Step-by-step explanation:

10.99 times 0.15 equals 1.55

10.99 + 1.55 = 12.54

Answer:

$10.99 + 15% = $12.63

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Answer:

x = 20

Step-by-step explanation:

Let's look at the first parallel lines (the ones with one arrow).

Because both these lines are parallel, we can say that (3x + 2) and (4x - 18) are equal due to the alternate interior angles theorem.

So we have to make both of these expression equal to each other, and then solve:

3x + 2 = 4x - 18

-x = - 20

x = 20            < --- this is your answer

Answer:

If simplifying, then

x^3 -13x^2 -x -49

Step-by-step explanation:

To do this, I would start off with the left side (use PEMDAS)

Use FOIL (First, Outside, Inside, Last)

x^3 + -9x^2 + 6x + -54 - (4x^2 + 7x - 5)

Bring negatives inside parenthesis

x^3 -9x^2 +6x -54 -4x^2 -7x +5

Combine like-terms

x^3 -13x^2 -x -49

(x^2 +6)(x-9)-(4x^2 +7x-5)

x^2 + 6 * x - 9 - 4x^2 - 7x + 5

x^2 + 6x - 9 - 4x^2 - 7x + 5

(x^2 - 4x^2) +(6x - 7x)+(-9 + 5)

(-3x^2)+(-x)+(-4)

=-3x^2 -x - 4

Answer: the answer is no

no, it is not a right triangle

Step-by-step explanation:

39 square+32.5 square=48.5 square

it's not the same so the result it no

Answer:

C. JK and LM are congruent

Step-by-step explanation:

Given the coordinates J(-2,8), K(0,8), L(1,0), and M(1,-2), in other to determine whether JK is congruent to LM, we need to determine if the length of side JK and LM are equal i.e JK = LM

To get JK:

We will find the distance between the coordinates J(-2,8), K(0,8) to get the length JK using the formula:

JK =√(x2-x1)²+(y2-y1)²

JK = √(0-(-2))²+(8-8)²

JK = √2²+0²

JK = √4

JK = 2

For the length of LM with coordinate L(1,0), and M(1,-2)

LM = √(1-1)²+(-2-0)²

LM = √0²+(-2)²

LM = √0²+2²

LM = √0+4

LM =√4

LM = 2

Since JK = LM = 2 units, this means that JK and LM are congruent.

Answer:

answer is A

Step-by-step explanation:

This symbol is called a tilde. In symbolic logic (a field of math  

used a lot in computer sciences) it is used to denote "not." For  

example, ~A means "not A." In some other contexts, it means  

"approximately." For example, pi ~= 3.1416. (Note that sometimes it is  

written above the equal sign, and sometimes it is used without an  

equal sign - it depends on the situation and the publisher.)

Answer:

g=2h-11

Step-by-step explanation:

You need to make the two sides equal, so add  6  to the left side:

[tex](g+5)+6=2h[/tex]

Solve for g

[tex]g+5+6=2h\\\\g+11=2h[/tex]

Isolate g

[tex]g=2h-11[/tex]

Answer:

18

Step-by-step explanation:

Look at all factors of 9 that are even; 18, 36,  54, 72, 90

Next divide 198 by those numbers and the only whole number is from 18.

9 x 2 = 18

198/18 = 11

Answer:

Answer:

x=− 3/8

​x=−2.667

x=−2

4.3     Solving    3x2+14x+16 = 0 by the Quadratic Formula .

According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :

           - B  ±  √ B2-4AC

 x =   ————————

                     2A

 In our case,  A   =     3

                     B   =    14

                     C   =   16

Accordingly,  B2  -  4AC   =

                    196 - 192 =

                    4

Applying the quadratic formula :

              -14 ± √ 4

  x  =    —————

                   6

Can  √ 4 be simplified ?

Yes!   The prime factorization of  4   is

  2•2  

To be able to remove something from under the radical, there have to be  2  instances of it (because we are taking a square i.e. second root).

√ 4   =  √ 2•2   =

               ±  2 • √ 1   =

               ±  2

So now we are looking at:

          x  =  ( -14 ± 2) / 6

Two real solutions:

x =(-14+√4)/6=(-7+)/3= -2.000

or:

x =(-14-√4)/6=(-7-)/3= -2.667

Step-by-step explanation:

Answer:

$54

Step-by-step explanation:

The original price was $90

The sale of the parrot is 40% off

40% * $90 = $36

The sale price = $90 - $36 = $54

Hence, the sale price of the parrot = $54
