Answer:

[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]

Step-by-step explanation:

[tex]2\left|3x-2\right|=14[/tex]

⇒ Divide both sides by 2

[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]

[tex]\left|3x-2\right|=7[/tex]

⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a

[tex]3x-2=-7\quad[/tex]

or...

[tex]3x-2=7[/tex]

Now,

[tex]3x-2=-7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=-7+2[/tex]

[tex]3x=-5[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]

[tex]x=-\frac{5}{3}[/tex]

[tex]3x-2=7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=7+2[/tex]

[tex]3x=9[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{9}{3}[/tex]

[tex]x=3[/tex]

Answer:

x = 3, PQ = 6 , PR = 12

Step-by-step explanation:

Given Q is the midpoint of PR , then

PQ = QR = 2x

PR = PQ + QR , that is

8x - 12 = 2x + 2x

8x - 12 = 4x ( subtract 4x from both sides )

4x - 12 = 0 ( add 12 to both sides )

4x = 12 ( divide both sides by 4 )

x = 3

Then

PQ = 2x = 2 × 3 = 6

PR = 8x - 12 = 8(3) - 12 = 24 - 12 = 12

Answer:

95+d

Step-by-step explanation:

Answer:

a. x = √400

b. x = +-20  (because 20^2 = 400)  It has two, positive and negative 20.

c. No, the -20 doesn't make sense because something can't have negative length.

d. 80 inches (20 * 4 = 80)

When a shape is dilated, the size of the resulting shape will either be bigger or smaller than the original shape.

The measure of side YW is 46

Given that:

[tex]k = \frac 34[/tex] ---- scale of dilation from [tex]\triangle WXY[/tex] to [tex]\triangle W'X'Y'[/tex]

[tex]Y'W' = 34.5[/tex]

This means that:

Side lengths of [tex]\triangle W'X'Y[/tex] = Side lengths of [tex]\triangle WXY \times k[/tex]

So, we have:

[tex]Y'W' = YW \times k[/tex]

Substitute known values

[tex]34.5 = YW \times \frac 34[/tex]

[tex]34.5 = YW \times 0.75[/tex]

Divide both sides by 0.75

[tex]46 = YW[/tex]

Rewrite as:

[tex]YW =46[/tex]

Hence, the measure of side YW is 46

Answer:

Q' = (-24, 20), R' = (-16, 16), and S' = (-2, 18).

Step-by-step explanation:

Recall that if a figure is dilated by a scale factor k (about the origin), then its coordinates become:

[tex](x, y) \rightarrow (kx, ky)[/tex]

In other words, we simply multiply each coordinate by the scale factor.

Triangle QRS with coordinates Q(-12, 10), R(-8, 8), and S(-1, 9) is dilated by a scale factor of two.

And we want to determine the coordinates of Triangle Q'R'S'.

Multiply each coordinate by the scale factor (two). Hence:

Q' = (-24, 20),

R' = (-16, 16), and

S' = (-2, 18).

Note: This method is only true when the figure is dilated about the origin.

Answer:

If 5 tennis balls are put into 4 boxes, with 5 tennis balls > 4 boxes, then at least one box will contain more than 1 tennis ball.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Well one of the first things you could do is put all 5 into one box. That means that that box contains at least 2 tennis balls.

Next being given to experiment, you put 2 balls in 1 box and 3 in another and the condition of 1 box containing at least 2 balls is still met.

So you do the best thing you can. You take 4 balls and put one in each box. So far you have not met the condition of the problem.

But you have one ball in your hand. Wherever you put the tennis ball, it must be in one of the boxes. That will meet the condition of the problem. One box has to have 2 balls in it.

7000

Step-by-step explanation:

lets start with 695

9 is the thousand

you check the number next to 9

less then 4 let it rest

more than 5 let it soar

something like that lol

anyways since 5 is next to the 9 we round up from 9 to the next number which is 10

so that changes the whole number to 7000

Answer:

No, you've already proven it's not irrational by writing it as 6/3.  You get 2.  

Step-by-step explanation:

An irrational number is any number that cannot be written as a fraction.

If we assume that point C is somewhere on segment AD, then,

AD = AC + CD

AD = (9x-12) + (4x+18)

AD = (9x+4x) + (-12+18)

AD = 13x+6    is the answer

Answer:

  C

Step-by-step explanation:

When you cross multiply by denominator expressions that share a zero, you are effectively making that zero a solution of the resulting equation. That zero cannot be part of the domain of the original equation, and so must be an extraneous solution.

This condition is seen in choice C.

  [tex]\dfrac{8}{x^2-9}=\dfrac{5}{2x-6}\qquad\text{original equation. $x\ne3$}\\\\8(2x-6)=5(x^2-9)\qquad\text{result of cross multiplying}\\\\16(x -3)=5(x+3)(x-3)\qquad\text{factored form}[/tex]

The solutions to this equation are x=1/5 and x=3. Of these, x=3 is extraneous.

__

A better solution method is multiplying by the least common denominator:

  [tex]2(8)=5(x+3)\qquad\text{result of multiplying by $2(x^2-9)$}[/tex]
