Answer:

x=8

Step-by-step explanation:

first you need to find the unknown corner so you do 180-71= 109

then find the interior angle degree (n-2)*180 (n=number of sides) so (4-2)*180=2(180)=360

then set everything equal to 360:

10x+6+13x-2+8x-1+109=360

(combine like terms)

31x+112=360

(subtract 112 form both sides)

31x=248

(divide both sides by 31)

x=8

Answer: Tiffany can be certain the trapezoids are congruent.

Step-by-step explanation: Two figures are congruent when their corresponding angles are equal and they have the same shape and size.

A figure can go thorugh 3 types of transformations:

As long the figure doesn't change its size or shape, it doesn't matter if it's rotated, reflected or translated, they will be congruent.

When the trapezoid was rotated creating another one, the two shapes didn't change its size or shape, so Tiffany can be certain they are congruent.

Answer:

Please check the explanation.

Step-by-step explanation:

Given the expression

[tex]2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2[/tex]

solving the expression

[tex]2\left(P\:+1\right)\:+\:3\left(P\:+\:2\:\right)\:>\:2[/tex]

as

so the expression becomes

[tex]5P+8>2[/tex]

subtracting 8 from both sides

[tex]5P+8-8>2-8[/tex]

[tex]5P>-6[/tex]

Dividing both sides by 5

[tex]\frac{5P}{5}>\frac{-6}{5}[/tex]

[tex]P>-\frac{6}{5}[/tex]

Therefore,

[tex]2\left(P+1\right)+3\left(P+2\right)>2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:P>-\frac{6}{5}\:\\ \:\mathrm{Decimal:}&\:P>-1.2\\ \:\mathrm{Interval\:Notation:}&\:\left(-\frac{6}{5},\:\infty \:\right)\end{bmatrix}[/tex]

- Area of rectangle = length * width

[tex]11 = 3\frac{2}{3} *w\\\\- rearrange and divide\\ 11 \\ by \\\\ 3\frac{2}{3}\\\\ = 3[/tex]

The side length of the rectangle is given by the equation L = 3 m

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the value of A is

A = 11 m²

Now , the width of the rectangle W = 3 2/3 m

Let the length of the rectangle be L

Now , Area of Rectangle = Length x Width

Substituting the values in the equation , we get

11 = L x ( 3 2/3 )

11 = L x ( 11/3 )

Divide by 11 on both sides of the equation , we get

L / 3 = 1

Multiply by 3 on both sides of the equation , we get

L = 3m

Therefore , the value of L is 3 m

Hence , the length of the rectangle is 3m

Answer:

In an equation, the two expressions are deemed equal which is shown by the symbol =. Where as in an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥. ... If the statement is true, the number is a solution to the equation or inequality.

Answer:

-3

Step-by-step explanation: Simplifying

2x + 6 = 0

Reorder the terms:

6 + 2x = 0

Solving

6 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 2x = 0 + -6

Combine like terms: 6 + -6 = 0

0 + 2x = 0 + -6

2x = 0 + -6

Combine like terms: 0 + -6 = -6

2x = -6

Divide each side by '2'.

x = -3

Simplifying

x = -3

Answer:

2x < 6

=> x < 6/2

=> x < 3

Answer:

True True False True

Step-by-step explanation:

You would substitute the value for x and the value for y into both equations and see if the sign holds true.

So for number 1:

x=3, y=-2;

y ≤ x -3        

-2 ≤ x - 3

-2 ≤ -1

y ≥ -x - 2

-2 ≥ -3 - 2

-2 ≥ -5

Number 1 is true because the equations are true ^^

Do this for every problem so it would be:

1. True

2. True

3. False

4. True

Answer: it would be C, -5/3

since slope = rise/run, or y2-y1/x2-x1 (either way works)

Answer:

the answer is C

Step-by-step explanation:

slope = rise/run, or y2-y1/x2-x1

You rise 5 to get to the point thats on the Y axis and you run left 3 to hit the point on the Y axis, so since you had to run left, that means its going to be negative but if you run right, the answer will be positive. i hope that helped :)

Answer:

2

Step-by-step explanation:

m is the slope = rise/run

take any 2 easi points on the line, for example (0,0) and (1,2)

to get from (0,0) to  (1,2) you had to rise 2 and go run 1 so the slope is

m=2/1=2

Answer:

Step-by-step explanation:

Given the formula to convert a temperature from degrees Fahrenheit (F˚) to degrees Celsius (C˚) as C˚=5/9F˚−1609.

To write the formula to convert °C to °F , we will make °F the subject of the formula

Add 1609 to both sides of the equation

C˚+1609=5/9F˚−1609.+1609

C+1609 = 5/9F

Cross multiply

9(C+1609) = 5F

Divide both sides by 5

9/5 (C+1609) = F

Hence the formula to convert from degrees Celsius to degrees Fahrenheit is 9/5 (C+1609) = F.

B) To check whether they are inverses we need to check if F(C) = C(F)

To get F(C) we will substitute F into C as shown;

F = 9/5 (C+1609)

C˚=5/9F˚−1609.

F(C) = 9/5 ((5/9F˚−1609.)+1609)

F(C) =  9/5 * 5F/9 -1609 + 1609

F(C)  = 9/5 * 5F/9

F(C) = 45F/45

F(C) = F

Similarly for C(F)

C(F) = (5/9(9/5 (C+1609))˚−1609.

C(F) = (C+1609) -  1609

C(F) = C

This shows that both equations are inverses of each other
