Answer:

  The conjecture cannot work for any negative numbers, It works for x > 1.3.

Step-by-step explanation:

An odd power preserves the sign. For |x| > 1, the power increases the magnitude. For x < 0, adding -2 only increases the magnitude more. A negative number of larger magnitude will not be "greater than" the reference. It will be "less than."

It only takes a counterexample to show the conjecture is incorrect.

  x^5 -2 ?? x

  (-2)^5 -2 ?? (-2)

  -32 -2 ?? -2

  -34 < -2 . . . . . . not greater than

An irrational number cannot be expressed as a ratio between two numbers and it cannot be written as a simple fraction because there is not a finite number of numbers when written as a decimal. Instead, the numbers in the decimal would go on forever, without repeating.

Answer:

Irrational number does not terminate and do not repeat. I hope this can make you understand what does irrational number is. Hope it helps you

Question:

Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26.

What is the solution set of this problem?

Answer:

[tex]x \leq -21[/tex]

Step-by-step explanation:

Given

Represent the number with x

So:

[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]

Required

Determine the solution set

[tex]5 * (x + 27) \geq 6 * (x + 26)[/tex]

Open Both Brackets

[tex]5 * x + 5 * 27 \geq 6 *x + 6 * 26[/tex]

[tex]5x + 135 \geq 6x + 156[/tex]

Collect Like Terms

[tex]5x - 6x \geq 156-135[/tex]

[tex]- x \geq 21[/tex]

Multiply both sides by -1

[tex]x \leq -21[/tex]

Hence, the solution set is [tex]x \leq -21[/tex]

Answer:

[tex]x\leq -21[/tex]

Step-by-step explanation:

Answer:

[tex]x = -9[/tex]

[tex]RQW = 22[/tex]

Step-by-step explanation:

Given

[tex]WQP = 139 + x[/tex]

[tex]RQW = 31 + x[/tex]

[tex]RQP = 152[/tex]

Required

Determine x and WQP

From the attachment;

[tex]RQP = RQW + WQP[/tex]

Substitute 152 for RQP, 31 + x for RQW, 139 + x for WQP

[tex]152 = 31 + x + 139 + x[/tex]

Collect Like Terms

[tex]152 - 31 - 139 = x + x[/tex]

[tex]-18 = 2x[/tex]

Divide both sides by 2

[tex]\frac{-18}{2} = x[/tex]

[tex]x = -9[/tex]

To solve for RQW; substitute -9 for x in RQW = 31 + x

[tex]RQW = 31 + (-9)[/tex]

[tex]RQW = 31 -9[/tex]

[tex]RQW = 22[/tex]

Answer:

36 × (how many games he buys) = (the price)

Step-by-step explanation:

36 dollars multiplied by the number of games he buys will equal the price.

Example:

Let's say he bought 3 games.

36 × 3 = 108

So, in this case, he bought three games using $108 .

Answer:

Step-by-step explanation:

Hello, I will compute twice the sum so I need to compute,

[tex]\begin{aligned}1&+2&+...+&(n-1)&+n\\\\n&+(n-1)&+...+&2&+1\\\\-&-----&---&---&---\\\\(n+1)&+(n+1)&+...+&(n+1)&+(n+1)\end{aligned}[/tex]

1+n = n+1

2 + n-1=n+1

...

n-1+2=n+1

n+1=n+1

So, this is n times n+1 so it is n*(n+1)

[tex]2(1+2+3...+n)=n(n+1)\\\\1+2+3...+n=\dfrac{n(n+1)}{2}[/tex]

Step-by-step explanation:

Answer:

[tex]\Large \boxed{\mathrm{Point \ C}}[/tex]

Step-by-step explanation:

Point C is located 5 units from points M.

Point C : (-1, 6)

Point M : (-6, 6)

Distance between two points:

[tex]d=\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2 }[/tex]

[tex]d=\sqrt{(-6-(-1))^2 +(6-6)^2 }[/tex]

[tex]d=\sqrt{(-5)^2 +(0)^2 }[/tex]

[tex]d = \sqrt{25} =5[/tex]

The distance between Point C and point M is 5 units.

Answer:point B

Step-by-step explanation:

Answer:

1a. A

1b. C

2 and 3 you have to draw

4a. 90 degree angle

4b. 180 degree angle

5a. 112 degrees

5b. 145 degrees

Step-by-step explanation:

for 5 you just subtract the given values from 360

Answer:

1a) A

(both B and C intersect at A)

1b) not sure

2a) draw 270 degree angle

360/4 = 90

90+90+90 = 270 = 3/4

2b) draw an angle less than 90 degree to get an acute angle

3a) first draw a 90 degree angle then divide the angle into two half and you ll get an angle of 45 degrees

90/2 = 45

but since you re not allowed to use compass or protactor so you might not get exact 45 but near to it

3b) draw a 90 degree angle facing downward and thats 270 degree

hope you get what im trying to say if not you can ask me again

4a) acute angle (90 degree)

4b) reflex angle (180 degree)

5a) 112 degree

118 + 130 + x = 360

248 + x  = 360

x  = 360 - 248

x  = 112

5b) 145 degree

360 - 215 = 145

im posting the solutions and the answers of your previous questions here

6a) a = 60 degree

6b) b = 27 degree

because sum of interior angles of a triangle is 180

7a) b = 60 degree and a = 30 degree

7b) x = 36 degree and x = 36 degree

isosceles triangle has 2 same angles and 1 different

x + x + 108 = 180

2x + 108 = 180

2x = 180 - 108

2x = 72

x = 72/2

x = 36

8a) x = 95 degree

8b) a = 100 degree

9) steps;

draw a line segment QR

draw 120 degree angle at point Q

now open the compass of 2cm (or of your own choice) and draw a small arc from point Q such that it intersects line PQ and QR and name that point between QR as O

now from point O, open your compass of same measurement and draw an arc that cuts the previous arc

now draw a line from point Q to join the new formed arc

now using a protactor measure both the newly formed angles

NO SOLUTION

Step-by-step explanation:

3/2x-2/3x=2

find the common denominater which is 6 and whatever you do to the bottom you have to do to the top, in turn you'll get

6/6x-6/6x=2

In this case since their both the same you subtract x from x and when you do that you get,

NO SOLUTION = 2

Answer: 27

Step-by-step explanation:

Answer:

c = 27

Step-by-step explanation:

Solve for c:

(2 c)/3 = 18

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (2 c)/3 = 18 by 3/2:

(3×2 c)/(2×3) = 3/2×18

Hint: | Express 3/2×2/3 as a single fraction.

3/2×2/3 = (3×2)/(2×3):

(3×2)/(2×3) c = 3/2×18

Hint: | Express 3/2×18 as a single fraction.

3/2×18 = (3×18)/2:

(3×2 c)/(2×3) = (3×18)/2

Hint: | Cancel common terms in the numerator and denominator of (3×2 c)/(2×3).

(3×2 c)/(2×3) = (2×3)/(2×3)×c = c:

c = (3×18)/2

Hint: | In (3×18)/2, divide 18 in the numerator by 2 in the denominator.

18/2 = (2×9)/2 = 9:

c = 3×9

Hint: | Multiply 3 and 9 together.

3×9 = 27:

Answer: c = 27

John already has 20 apples. If John gets 1 more apple, he would have 21 apples in total.

The word gets means addition. 20 plus 1 equals 21.

John has 21 apples after he gets another apple.

Ok technically I would have 0 apples since I didn't receive any only John did.

Answer: [tex]\frac{6(#30)+3(20)}{60}[/tex]

Step-by-step explanation:

=4 hours

Answer:

21). WX = 10

22). VW = 22

23). WY = 20

24). VX = 32

25). WZ = 30

26). VY = 42

Step-by-step explanation:

In the figure attached,

V, W, X, Y and Z are collinear.

VZ = 52, XZ = 20 and WX = XY = YZ

21). Since XZ = 20

     XY + YZ = 20

     WX + WX = 20 [Since, XY = WX = YZ]

     2(WX) = 20

     WX = 10

22). VZ = VW + WX + XY + YZ = 52

     VW + 3(YZ) = 52 [Since, WX = XY = YZ]

     VW + [tex]3(\frac{XZ}{2})[/tex] = 52

     VW + [tex]\frac{3}{2}\times 20[/tex] = 52

     VW = 52 - 30 = 22

23). WY = WX + XY

             = 2(WX)

             = 20

24). VX = VW + WX

             = 22 + 10

             = 32

25). WZ = 3(WX)

             = 30

26). VY = VZ - YZ

            = 52 - 10

            = 42  

Answer:

(B) Subtract 3x from both sides of the equation, and then divide both sides by 2.

Can't read the second question fully.

(A) 0.53

Step-by-step explanation:

Number 1:

If we have the equation [tex]3x + 2 = 5x[/tex], our first goal is to get rid of the x term on one side.

To do this we can subtract 3x from both sides. This leaves our equation to [tex]2=2x[/tex]. To find x, we want to divide both sides by 2 since 2x divided by 2 is just x. Our goal is to isolate x.  This leaves [tex]x=1[/tex].

I couldn't read Number 2 fully - I'm sorry :c

Number 3:

Given the equation [tex]3(x+0.2)=2.2[/tex], we want to isolate x on one side.

To do this, we first apply the distributive property to the left side.

[tex]3x + 0.6 = 2.2[/tex]

Now subtract 0.6 from both sides:

[tex]3x=1.6[/tex]

And divide both sides by 3.

[tex]x=0.5\overline{3}[/tex]

This rounds to 0.53.

Hope this helped!

Answer:

B

28.78

A

Step-by-step explanation:

Equation

3x + 2 = 5x

The first step is to subtract 3x from both sides.

3x - 3x + 2 = 5x - 3x

2 = 2x

The next step is to divide by two. That's the 2 in front of the two x.

2/2 = 2x/2

1 = x

So the answer must be B

The others are just not done in the right order and give wrong answers.
