Answer:

Basically if its a non-terminating:non-repeating decimal its irrational.

For Example:Pi:π = 3.141592…as you may know it goes on into infinity without a specific pattern to it

Answer:

x= 13

y= 39

Step-by-step explanation:

Answer:

x = 29

Step-by-step explanation:

The sum of the 3 angles is 180 degrees since it is a straight line

x-1 + 3x+2  + 2x+5 = 180

Combine like terms

6x +6 = 180

Subtract 6 from each side

6x+6-6= 180-6

6x =174

Divide y 6

6x/6 =174/6

x = 29

Answer:

it's 29

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

1. b⁵

2. +16m⁹

Step-by-step explanation:

1. Add exponents: b³⁺² = b⁵

2. Negative and Negative = positive

2*8 = 16

m⁴⁺⁵ = m⁹

Hence: + 16m⁹

Answer:

[tex]1) \: {b}^{5} [/tex]

[tex]2) \: \: + 16 {m}^{9} [/tex]

Step-by-step explanation:

[tex] {b}^{3} \times {b}^{2} = {b}^{3 + 2} = {b}^{5} [/tex]

we know that

[tex]( - ) \times( - ) = ( + )[/tex]

So

[tex] - 2 {m}^{4} \times - 8 {m}^{5} \\ = + 16 {m}^{9} [/tex]

Answer:

(x/4)(x-2)

(x-6)(x-3)

Step-by-step explanation:

Answer:

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

x - y = 1 ( add y to both sides )

x = y + 1 ( subtract 1 from both sides )

x - 1 = y , that is

y = x - 1 ← in slope- intercept form

Answer:

16 bombons de coco

Step-by-step explanation:

A partir da pergunta, somos instruídos a fingir que o número total de bombons (chocolate) que ela fez = 24 bombons

Do total de chocolates que ele fez, 2/3 são de coco.

Portanto, a quantidade que representa os doces de coco é representada como:

2/3 × 24

= 16

Portanto, a quantidade de bombons de coco = 16

Answer:

Answer:

w=-y+1/2x

Step-by-step explanation:

Its literal equations, so just solve like any other variable equation. Set your w value to the equal, and isolate the said variable

Answer:

C) y = 1/3x - 6

Step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

1/3=m

-6=b

then plug in the numbers to get: y=1/3x - 6

[tex]f(x) = {2}^{x} [/tex]

You can answer them yourself but I like to help you to do it buddy.

Let's go....

[tex]f(1) = {2}^{1} = 2 [/tex]

[tex]f(2) = {2}^{2} = 4 [/tex]

[tex]f(3) = {2}^{3} = 8 [/tex]

[tex]f(4) = {2}^{4} = 16 [/tex]

[tex]f(5) = {2}^{5 } = 32 [/tex]

[tex]f(6) = {2}^{6} = 64 [/tex]

And we're done.

Thanks for watching buddy good luck.

Answer:55.25 or 6.25

Step-by-step explanation:

Answer:

4x^2 - 2x + 1

Step-by-step explanation:

Since you are adding, you can drop the parentheses because they are unnecessary. Combine like terms.

(3x^2 - 2x + 1) + (1x^2) =

= 3x^2 - 2x + 1 + 1x^2

= 4x^2 - 2x + 1

Answer:

The area of the polygon CDEFGH is 7

Step-by-step explanation:

Area of a Polygon

The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.

The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:

The area CDHE is a square of length side 2. Area of a square:

[tex]A1=L^2[/tex]

The area HEFG is a trapezoid with bases lengths 4 and 2,  and height 1. Area of a trapezoid:

[tex]\displaystyle A2=\frac{b1+b2}{2}h[/tex]

Calculate both areas:

[tex]A1=2^2=4[/tex]

[tex]\displaystyle A2=\frac{2+4}{2}\cdot 1=3[/tex]

Total Area=4+3=7

The area of the polygon CDEFGH is 7

Answer:

Step-by-step explanation:

You multiply 18.99 with 0.065 to see how much extra money you have to pay. Then you add it back to 18.99 for the final cost.    

Answer: -0.56 (with a line over the 5)

Step-by-step explanation:  I found my answer by dividing 5.000 by 9 which is 0.56. Then, I wrote a line over the 5, so that I don’t have to repeat the number 5, multiple times.
