Answer 2

Answer:

-12x+4

Step-by-step explanation:

First, you have to rearrange terms.

-6(-2/3+2x)

-6(2x-2/3)

Now you have to distribute.

-6(2x-2/3)

-12x+4

and that's how you get your answer.

I hope this helps.      :)

(You can also put it as 4-12x.)

Find the slope from the given table:
х Y
-3. 8
0. 7
3. 6

Answers

The answer is plus +3 for slope
Well, if we were to calculate slope from a graph, then we would look at the rise/Run but since we have to calculate it from a table of values, we will look at the first differences. In rise/Run, the rise is the Y while the X is the run so, on that basis, we can calculate the slope it rate of change from this table of values.
1. Rise = Y
We can see that each time that we are going to the next term, we are subtracting by and going down by 1 so, our rise is -1 while when we look at our run, each time, we are adding 3 units to get to the next term, so our Rise/Run would by -1/3.

So, in conclusion, the slope from the given table is: -1/3.

The perimeter of a rectangular area is 16ft.
Write an expression for the sum of the length and width.

Answers

Answer:

Length + Width = 8 ft

Step-by-step explanation:

"The perimeter of a rectangle is 16 ft."

A perimeter is the sum of four sides of a rectangle.

OR...

Perimeter = Side 1 + Side 2 + Side 3 + Side 4

A rectangle has "matching sides", so...

Length: Side 1 = Side 3

Width: Side 2 = Side 4

Therefore we can just say that:

Perimeter = (Length * 2) + (Width * 2)

We can pull the 2 out:

Perimeter = 2 * (Length + Width)

Since Perimeter = 18

16 = 2 * (Length + Width)

Divide both sides by 2

8 = Length + Width

Length + Width = 8 ft

Answers

Answer:

a).cruz is right.

b).-64 is cube root of -4.

c).because -64 is square root of -8.

Step-by-step explanation:

1.Cruz is right

2. If the nth root of the negative number is a odd number, the answer is negative this of the FOLLOWING is the example not the answer

[tex] \sqrt[5]{ - 243} = [/tex]

[tex]( - 3 \times - 3) = 9[/tex]

[tex]9 \times ( - 3) = - 27[/tex]

[tex] - 27 \times - 3 = 81[/tex]

[tex]81 \times - 3 = - 24 3[/tex]

So the answer is -3

For -64

[tex] - 4 \times - 4 = 16[/tex]

[tex]16 \times - 4 = 64[/tex]

So Cruz is right.

3. Aaron is wrong because it asked for the 3rd root of -64 and -8 isn't that.

Jacob is wrong because the nth root is a odd number and the number under the radical s negative so it going to give us a negative number(which is a real number)

The radius of the button will be 14 millimetres.

What is the radius of the circle?

The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.

Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,

Radius = Diameter / 2

Radius = 24 / 2

Radius = 12 millimetres

Therefore, the radius of the button will be 14 millimetres.

Answer : 19.5m


The area formula for a trapezoid is A = a+b
——h
2
You would cut the trapezoid vertically then you would do 4x3=12 then 3x5...3 because you subtracted 6-3, so 3x5 is 15 then 15/2 would be 7.5 you divided bc it’s a triangle and the formula for the triangle is A=bxh/2
Then lastly you would add 7.5 + 12 and you’d get 19.5m.

Answers

Answer:

x = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = [tex]\frac{6}{8}[/tex]  <----- to reduce, divide the numerator and denominator by 2

Hence,

x =  [tex]\frac{3}{4}[/tex]
